Keeping up with Retirees

Bryant Rossiter Update
Ed Przybylowicz writes:  
I had a call from Bryant Rossiter on my voicemail which I answered yesterday, May 25, 2021. We had a nice 45 minute conversation. Bryant retired in 1986 and moved to Laguna Hills, CA where he and Betty lived until 2 years ago when they moved to Springville, Utah into senior housing. Betty passed away in November 2020 at 92 and Bryant celebrated his 90th birthday this past year. He asked about a lot of colleagues from his years at Kodak. As some of you know he was very active in the Mormon Church and that activity continues during his years in Laguna Hills and even now he appears to be active in the governance of the Church. He has some family nearby Springville which is a suburb of Provo, UT. He still has a son living in Rochester. He asked to be remembered to the KRL community members.

Ken Reed Designs COVID Facemask
Ken writes "To make some contribution to defending against the COVID-19 virus (other than pulling the bed sheets over my head in the morning and refusing to get out of bed), Shirley and I have designed some face masks that we feel offer superior protection against not only this but other future viruses (perhaps even nerve gas agents). Here are some abbreviated technical aspects of the mask (now in the third generation which is why i am releasing it now). At this point I have about $ 7K sunk costs in the mask (materials and two patent applications) so I pretty much can’t afford to give them away free anymore but at cost ($20).

Ching Tang Awarded 2019 Kyoto Prize
In recognition of pioneering research that has resulted in a form of 
light-emitting diode that is ubiquitous in smartphones and flat-
panel displays, Ching Tang, a professor emeritus of chemical 
engineering, received the 2019 Kyoto Prize this winter.

Recognized as the laureate in advanced technology, Tang is 
credited for making possible organic light- emitting diodes (OLEDs).
The high-efficiency, organic-based devices have helped 
revolutionize lighting, screen display, and computer technology. 
Considered one of the world’s most significant recognitions of 
scientific, cultural, and spiritual contributions to humankind, the award was established in 1984 by the nonprofit Inamori Foundation.

Tang graduated with a BS in chemistry from the University of British Columbia, Canada, and
earned his PhD in physical chemistry from Cornell University in the US in 1975. He joined Eastman Kodak in 1975 as a Research Scientist, was promoted to Senior Research Scientist in 1981, to Research Associate in 1990, and to Senior Research Associate in 1998. In 2003 he was named Distinguished Fellow of the Kodak Research Laboratories, Eastman Kodak Company. In 2006 he joined the University of Rochester as the Doris Johns Cherry Professor.

Bob Bacon Reminiscences on Al Millikan​

Peter Dillon and Al Brault Receive Technology Emmy Awards
Peter Dillon and Albert Brault were recognized by the National Academy of Television Arts & Sciences with Technology Emmy Awards for developing the single-chip color camera widely used to produce television programs and movies. 

In 1974, Dillon and Brault, then at Kodak Research Labs (KRL), developed a prototype color video camcorder. Instead of the conventional design using a large color prism and three CCD (charge coupled device) sensors, Dillon came up with the idea of fabricating a color filter mosaic over the individual pixels of a single CCD. Brault then perfected a process for coating organic color dyes through photoresist windows during wafer fabrication. 

To determine the optimum color pattern, Dillon consulted KRL mathematician Bryce Bayer, who invented the checkerboard arrangement now known as the “Bayer Pattern.” These concepts made capturing color digital images inexpensive.

The single-chip color sensors and video cameras pioneered by Peter Dillon and Albert Brault decades ago have materially affected today’s television viewing experience,” Seidel said.

Both Peter Dillon and Al Brault continue to live in the Rochester area.​

John Monnier inducted into National Academy of Engineering
Former Kodak Research Labs employee John Monnier was inducted into the National Academy of Engineering in 2017 for discovering/developing the industrial process for selective epoxidation of 1,3-butadiene to form 3,4-epoxy-1-butene (EpB) and many subsequent derivatives made from EpB, including 2,5-dihydrofuran, 2,3-dihydrofuran, 1,2-epoxybutane, crotonaldehyde, and cyclopropyl carboxyaldehyde, among others. The discovery phase of these projects were done in Kodak Corporate Research Labs from 1987 – 1993, when CORL ended. From 1993 – 2004 he worked at Eastman Chemical Research in Kingsport, TN to scale up these processes at Texas Eastman in Longview, TX. He retired in 2004 as a Technology Fellow and moved to the University of South Carolina, where is currently Professor of Chemical Engineering.

Dick Kurz posthumously joins St. John Fisher Science & Technology Hall of Fame

Established in 2011 by the College’s Science and Technology Alumni Group, the Hall of Fame recognizes individuals who are noteworthy for their service to their community or the College.

A member of the third graduating class at St. John Fisher College, Dick Kurz spent nearly 30 years at the Eastman Kodak Co., where he worked in the developing radiographic films, commercial and portrait films, x-ray films, dental films, graphic arts and micrographic films. While most of his discoveries were held as internal trade secrets, he was granted 4 patents for his work in this area and authored over 100 internal technical reports. He was also highly innovative in management processes.

Kurz excelled in advocating and building a better world for those in need and for those who struggle to speak for themselves. He was a long-time board member of the United Cerebral Palsy Association, serving twice as board president. He was a founding member of the Montessori School of Rochester. Kurz worked on the initial fundraising campaign for the Al Sigl Community of Agencies. He was a stalwart member of his community, serving as a lector and member of several committees through Holy Name of Jesus and Peace of Christ parishes. In his later years, he tutored fourth-grade students in science.  

Ching Wan Tang and Steven Van Slyke recognized by the National Inventors Hall of Fame (NIHF)

Chemists Ching Wan Tang and Steven Van Slyke pioneered organic light-emitting diodes. OLED displays represent an advance in flat panels that provides increased power efficiency, longer battery life and improved display quality. They are among 15 innovation pioneers who will be honored in May as part of the newest class of Inductees in the National Inventors Hall of Fame.

Tang joined Eastman Kodak in 1975. He hired Van Slyke, and together they applied the organic heterojunction--a bilayer structure of an electron donor and an electron acceptor invented by Tang--to various applications including OLEDs.

Van Slyke said that in the period that they were perfecting OLED display technology, the duo’s philosophy was to “always get one more experiment done.” They would end up staying much later in the night than they had intended.

OLEDs can be used wherever LCDs are used. They are thinner, lighter, provide superior brightness and color, and offer fast response time for functions such as refreshing and on-off switching. Unlike LCDs that rely on a backlight that passes through color filters to produce light, OLED screens utilize luminescent organic materials to make their own light.

The first OLED product was a display for a car stereo, commercialized by Pioneer in 1997. Kodak’s EasyShare LS633 digital camera, introduced in 2003, was the first consumer electronic product incorporating a full-color OLED display.

Today, Samsung uses OLEDs in all its smartphones, and LG manufactures large OLED screens for premium TVs. Other companies incorporating OLED technology include Apple, Google, Facebook, Motorola, Sony, Hewlett-Packard, Panasonic, Konica, Lenovo, Huawei, BOE, Philips and Osram. The OLED display market is expected to grow to $57 billion by 2026.

Tang and Van Slyke will now join innovation luminaries such as Thomas Edison, George Washington Carver, Steve Jobs and Hedy Lamarr in the National Inventors Hall of Fame.

Each year, NIHF accepts nominations from any outside source for patented inventors who have had an impact on our lives. Nominations are researched and vetted, and intellectual property status of the inventions involved is also examined.

As the research process progresses, a list of candidates is put in front of a National Selection Committee made up of representatives from national science, technical, engineering and intellectual property organizations. The committee reviews, discusses and comes to consensus on the next year’s group of Inductees. Their recommendation goes on to the NIHF Selection Board, which reviews, discusses and ratifies the final slate.

Carl Kohrt writes...
I so wish that I could make it up to Rochester for the KRL luncheon. I get a bit nostalgic every time I receive one of your missives, and would like to reconnect with KRL colleagues.

Lynne and I continue to live in NW South Carolina 40 miles west of Greenville on Lake Keowee within 5miles of the Blue Ridge Mts. We are in or on the water as much as we can be, and I hike to the nearby waterfalls (50+ of them) within the limits of my ageing chassis. Otherwise, the warm water (and no, its not due to the nuclear power station 4 miles away on the lake) was an attraction to our three families and 10 grandchildren this summer--three of whom are at nearby Furman (my alma mater) and one at Case Western Reserve. Of course we all enjoyed the total eclipse from the exact center of the course as it passed from Greenville to Charleston.

I spent the summer teaching Operations Management to the university evening school at Furman--gave me a chance to share "stories" -- many of them would be recognized by other KRL folks. Believe it or not, some of the stories were actually true--but the students couldn't tell which ones! The irony was that the textbook was authored by Professor Stevenson of RIT--so kept it all close to Rochester, including many case studies of Wegmans (but none of Kodak).

Please extend my best wishes to all,

Carl and Lynne Kohrt (August 2017)

Stephen Hofner presents...

Kodak research scientist Louis M. Condax is often referred to as “the father of the Kodak Dye Transfer process.” Researcher Stephanie Hofner will discuss the significance of Condax’s achievements, providing an overview of his career and his contributions to the development of Dye Transfer at Kodak Research Laboratories. The talk is at noon, Saturday, June 17th, at the Curtis Theater of the George Eastman Museum.

Carl Kohrt writes...
Thank you for the invitation for the May KRL Retiree Luncheon. I will not be able to make the drive from SC to attend. Please extend my best wishes to my former colleagues. I think of the good work done by them with pride.  

After our unexpected service as Interim President and First Lady to Furman University ended and the new President installed this March we returned to Lake Keowee at the base if the Blue Ridge Mts. I continue to work with start up companies as investor, mentor, or board member --winning some and losing some as is the nature of the genre. The real fun of course is family.        April 8, 2015

John Monnier KRL (1972-1993) and Eastman Chemical Research Labs (1993-2004) writes…

I am now in my 10th year as a Research Professor of Chemical Engineering at the University of South Carolina in Columbia, SC, and have continued research in the area of heterogeneous catalysis, particularly the use of bimetallic catalysts. We use a modification of the method of electroless plating developed by Joe Yudelson, when I was a member of his research group at Kodak.  Rather than plating, we use the method to deposit sub-monolayers or even 1-2 monolayers of a second metal on a primary metal to produce novel, and well-controlled, bimetallic catalysts.  These materials have been used very successfully for reactions ranging from direct methanol fuel cells to selective glycerol oxidation to selective hydrogenation of acetylene in ethylene cracking streams.  All of my PhD students have gone on to very successful careers in industry and academia.  I anticipate doing this for another 5 – 10 yrs, if possible.  Interestingly, I draw upon my background at KRL almost daily in my research projects-the greatest “university environment” I have ever experienced.

Tony Kaye honored
Tony Kaye (formerly of Harrow R&D) and his wife Deanna have been awarded the 2013 Ernie Heath Shield by national charity Ataxia UK, in recognition and honor of their outstanding contribution to people affected by ataxia.

Ataxia means ' lack of order' and is the term given to a group of neurological conditions that affect balance, coordination and speech. In some cases, people get the symptoms of ataxia for short periods of time and then recover. In many cases ataxia is permanent, progressive (i.e. the symptoms get worse over time) and life limiting.

Deanna, who has cerebellar ataxia, and Tony have a long association with Ataxia UK, running its North West London Branch, raising funds and awareness, and volunteering at the London Specialist Ataxia Clinic at the National Hospital for Neurology and Neurosurgery in Queen Square. The couple has raised over £6,000 for the charity, and Tony has also volunteered his professional photography skills to record several events.

Bill Staudenmeyer writes 
"In my retirement I have pursued 'Recreational Science' investigations, following some interesting chemistry and physics frontiers.   A sign of vitality is robust controversy with serious discussion and investigation, often leading to progress.  New concepts emerge and gain respectability but only after healthy skepticism.  Even then, questions can linger, such as whether some of the non-intuitive claims of conventional quantum mechanics can in fact have alternative explanations.

I have followed two forums as  examples of opposing viewpoints:  (1) the Susskind Lectures (stanfordcontinuingstudies/, as the established mainstream, presenting the 'theoretical minimum' of modern physics, and (2) the new work of Randell Mills (, undoubtedly controversial, but with enough supportive evidence to be at least intriguing.  Examples of issues where these two contenders would vie are:  hydrogen ground state vs. hydrino fractional states,  H electron orbit stability vs. Haus/Goedecke radiation criteria,  Higgs boson vs. precisely calculated particle masses using fundamental constants only,  unidentified dark matter vs. hydrino proposal, and as derivatives, several new potential energy sources.

This would seem to deserve more attention, if only because of the potential benefits to all.   The absence of serious outside experimental work to follow up Mills publications, which invite reproducibility investigations, is glaring.  Perhaps this is explainable because the initial hydrogen work was mistakenly identified with the Cold Fusion fiasco.  Nor was it helped by the scope of Mills claims.  But the chemistry is quite different, and the actuality here seems to be extraordinary.  Several books have already been written, including one by Mills, along with over 90  journal publications with his collaborators.  An example is a paper by Mills et al in EurPhysJourD2011, reporting experimental measurement of novel extended UV continuum emission spectra accompanying hydrino formation, with emission edges corresponding to the 1/3 and 1/4 fractional H states.  The journal editors made a special plea for outside reproducibility investigations, but nothing has appeared.

So, a question to be considered is, what exactly is wrong here ?" (8/22/2013)

Nick Zumbulyadis  is part of team to study chemical mechanisms behind the deterioration of famous paintings

A research program developed jointly by Dr. Nicholas Zumbulyadis (KRL retiree, 2005), Dr. Silvia Centeno, research scientist at the Scientific Research Department of the Metropolitan Museum of Art and Dr. Cecil Dybowski, professor at the Department of Chemistry and Biochemistry of the University of Delaware has received funding by the National Science Foundation (NSF). The project is supported through NSF’s Cultural Heritage Science program, and will use solid state nuclear magnetic resonance techniques to study the chemistry behind the gradual deterioration of significant paintings, among them iconic works by Rembrandt van Rijn and John Singer Sargent.

Solid state nuclear magnetic resonance (NMR) is an advanced analytical technique for the characterization of molecular structure and dynamics and is now a well-established tool for solving problems in biochemistry, polymer chemistry and materials science. While at Kodak, Dr. Zumbulyadis pioneered the application of solid state NMR to the characterization of pigments and coatings used in various imaging technologies. Prof. Dybowski has done fundamental work in solid state NMR at the University of Delaware. Dr. Centeno uses vibrational spectroscopy and other analytical techniques to investigate and help preserve works of art at The Metropolitan Museum of Art. 

The grant also funds the creation of a three-year postdoctoral position for a recent graduate with a PhD in chemistry.

Carl Kohrt  
writes "As many of you know (or suspect) Carl and Lynne Kohrt once again find themselves in a "retired state" as of December 31, 2008.  Carl retired after 7 1/2 years as President and CEO of Battelle Memorial Institute in Columbus, Ohio.  It was a good run, as they say, with revenue growing from 1B to nearly 5B with an emphasis on running 6 of the US National Laboratories for the Departments of Energy and Homeland Security as well as contract research in energy, infectious disease, and homeland security.  Some of this growth and subsequent impact was fueled by my joining two weeks after 9/11 and we were soon called on by the government to help solve some major problems in security.  My successor, Dr. Jeffrey Wadsworth, also enters at a time of crisis when good science and its application will be brought to bear in areas of energy and disease.  Jeff is a member of the National Academy, a metallurgist and an expert on ancient swords.  He has most recently been the Laboratory Director of Oak Ridge National Lab, Deputy Director of Lawrence Livermore National Lab, and a research manager at Lockheed.  He came to Battelle 6 years ago, so our transition has been fabulous as we built a strategy and management team together.

"In the meantime, Lynne has found that I am badly in need of some remedial training, as we are having too many "close encounters of the wrong kind" in certain areas of the house.  We plan to leave Columbus, Ohio,  by mid-summer and set up our residence, once again, in Salem, SC where we have a home on the water near the mountains and Furman University, my alma mater.  Of course in today's economy, our real estate listing on our house may outlast my lifetime--anyone interested?  On the business side, I sit on the boards of two public companies that are growing their R&D investments:  Scotts Miracle-Gro (SMG) and Kinetic Concepts Inc (KCI).  KCI has a Kodak connection through its CEO, Cathy Burzik, who began her career at Kodak in clinical diagnostics R&D and was part of the Health Sciences Division and corporate planning before leaving to become President of a J&J division.  She and her husband, Frank (a former engineer at Elmgrove) are living in San Antonio where they are competitive ball-room dancers on the few days Cathy is in town. I also am helping Battelle finish two Asian deals in Malaysia and China (surprised?) that will take me to far away places a couple of time this year.  Yea, I know, I know it is time to slow down.  We do hope that this finds our friends and colleagues in good spirits and good health."

Wolfgang Gunther 
writes "My wife Helge and I  continue our traveling lifestyle. Our trip to the Galapagos islands in May07 on a small vessel with only nine fellow passengers was a wonderful experience and is recorded on a 120 minute DVD, the best we have ever produced. Wolfgang also delivered the introductory lecture at ICCST-10 [International Conference on the Chemistry of Selenium and Tellurium] in Lodz, Poland in June07 in the form of a commemorative DVD. Wolfgang started the series in 1971 and it has become an unexpected,  self-propagating success. Incidental to this is the Selenium and Tellurium Interest Group, SeTeIG, a discussion list that Wolfgang is hosting and that has currently 163 world-wide subscribers.

"In Fall 2007 we visited old haunts in England, like Leeds where we first  met, London where Helge got her Ph.D, and Manchester to attended the wedding of a young friend. We also saw Stonehenge in real life for the first time. Massachusetts' Patriot's Week in April 2008 found us exploring Hawaii with our two youngest grandchildren, paying off on a promise made 5 years ago when we had taken the two older ones (who are now in college). In March 2008 we had our 50th wedding anniversary but delayed celebration until July (better traveling weather) for a wonderful and well attended party thrown by our children. And the ACS  gave Wolfgang a pin and a free lunch in honor of being a 50-year member. The ACS Philadelphia Section can actually boast of one 70-year member who also attended the luncheon. Sept./Oct. will find us in Campos do Jordão, Brazil to present a DVD update of the ICCST presentation by invitation of the organizers of 'II Encontro sobre Selênio e Telúrio - Brasil' ( Attendance at the conference will be preceded by a photographic wildlife expedition in the Belo Horizonte, Minas Gerais, area of Brazil.Wolfgang also continues to host eSterlinK, an online mail list of former Kodak/Sterling employees.
