2017 Outstanding HS Chemistry Teachers
Each year, up to two winners are selected for the Princeton and Trenton ACS Sections’ Outstanding High School Chemistry Teacher Awards,
This year they are:
Emilie Gingras – The Hun School of Princeton
Carolyn Wilhelm – North Hunterdon High School
The evaluation criteria for this award are the quality of their teaching; their leadership (classroom and profession) ; keeping up to date in the field; extracurricular work in chemistry and teaching; emphasis on laboratory safety.
Emilie Gingras received a BS in Chemistry in 2006 and MS in 2008 from the Université Laval, Québec, Canada.
Emilie has been teaching since 2013, and joined the The Hun School of Princeton in 2016 where she teachers five regular chemistry classes.
Prior to teaching, she was a Technical Sales Representative for Corporation Scienfique Claisse.
These quotes from her letters of recommendation reflect why she was selected as one of our winners:
“Emilie teaches her students not only the importance of mastering scientific reading, writing, and logical reasoning skills, but also the ability to chart their own progress as thinkers, gaining self-confidence and self-esteem in the process…..
Emilie is able to adapt the explanations of scientific concepts to different learning styles in ways that I’ve seen many new and experienced teachers miss.”
“Her classroom is alive with collaboration and discussion and her students see clearly how invested she is in their success. Additionally, as a professional, Emilie is intent on self-improvement, consistently seeking new opportunities to learn from her colleagues and from any source of professional development that she can find.”
Our second awardee is Carolyn Wilhelm.
Carolyn received a PhD in Food Science from the University of Massachusetts in 1990 and BS degrees in Food Science and Nutrition Science from Drexel University in 1985.
She has been teaching since 2002, and joined North Hunterdon High School as a chemistry teacher in 2007 where she teaches College-Prep, Honors and AP Chemistry.
Prior to teaching, she was a research associate at Nabisco Inc. from 1991 to 1997 and a Freelance Technical Writer 1998 to 2001.
It is clear from Carolyn’s nomination information that she is dedicated to chemistry education. For example, in the final weeks before the AP exams, she meets with her students at night in the town library to prepare them for the exam.
She also organizes a Science Night at the local elementary school where she and her students conduct demonstrations and teach mini lessons on chemistry. Her efforts have been instrumental in increasing Hunterdon’s AP Chemistry scores and increasing interest in science at the elementary school level
As quoted in one of her letters of support “One of the most unique abilities of Dr. Wilhelm is her positive influence in motivating and attracting students to the field of science. Her caring attitude and superior knowledge of the subject matter make her effective at all levels. …..Her creative and innovative approach has earned her much respect among her peers, students and the community.”

My 50 Years in Chemistry
by John Berrier
Chemistry allowed me to continue learning during my entire career and has been quite a journey in ways I never could have imagined.
What really excited me about chemistry as a career was an NSF summer course I took at Bucknell University after my junior year of high school. In six weeks, it provided a taste of general chemistry, structural organic chemistry, and organic reaction mechanisms. As a result, I applied only to Bucknell, because it offered organic chemistry for freshman. That led to enrollment in a combined BS-MS program after my sophomore year. Three summers of research and extra courses during the school year led to both degrees in the summer of 1967.
During graduate school at Princeton University on an NSF Fellowship, I carried out research on the synthesis of pteridines with Ted Taylor. While purifying an intermediate for functionalizing pteridines, I discovered an aromatization reaction involving N-oxides which led to riboflavin analogs. I found this to be a prime example of the theme of Hubert Alyea’s famous lecture, “Accidents and the Prepared Mind”. It was also exciting to be a teaching assistant for Alyea.
For seven years, I taught Organic, General, and Nursing Chemistry at Anne Arundel Community College in Annapolis, Maryland. I enjoyed the interaction with students and felt that I learned some aspects of physical and bio-chemistry better than when I took the courses, but missed research, so I took a summer job with Alcolac in Baltimore. My most memorable assignment there was to instruct the operators on a kettle-side analysis of a process to ethoxylate a railroad car full of hydrogen sulfide.
After deciding to switch to full time research, I went to Crompton and Knowles as a process chemist just as they bought parts of the dye businesses of Ciba-Geigy and DuPont. I was responsible for the introduction of over a dozen dyes into the plant, on as large a scale as 10,000 gallons. The most challenging involved five parallel diazotizations and couplings to prepare a brown leather dye for Hush Puppies.
Before retiring as a Distinguished Scientist in 2008, I spent 27 years at Rohm and Haas in Philadelphia as a process chemist in the Agricultural Business and then Biocides. I developed processes for new commercial products, led process improvement projects at plants in Philadelphia, Texas and England, and participated in the design and operation of two new plants in China. For one product, the surprising observation on a small scale of a 100 degree difference in boiling points between isomers led to development of a simple thin film evaporation process to remove the major impurity. For another, knowledge of the chemical and physical properties of impurities in a decades-old product led to a no investment purification process which raised the final purity from less than 90% to over 99% (the first plant batch had a higher purity than the analytical standard) and enabled re-registration of the product under modern regulations. Finally, I shared in the development of a commercial process which used phosgene and hydrazine as safer alternatives to the ingredients used in the discovery process.
Overall, it has been an interesting and eventful journey, both in miles and experiences.
