Gertrude B. Elion (1918-1999)
June 1993
Gertrude Elion shared the 1988 Nobel Prize in physiology/medicine.
Her major achievements included the development of drugs to treat leukemia, gout, herpes virus infection, and to prevent rejection in organ transplants.
At the age of 15, she chose a career in molecular sciences and decided to go into cancer research to find a cure for cancer. In 1937, she earned a bachelors degree with highest honors from Hunter College. Living at home, and working as a high school teacher, she took evening classes and earned a masters degree in chemistry from New York University in 1941.
She experienced discrimination in the 1940s and had a difficult time finding a job that matched her ability and training. But since male chemists were away there was a need for chemists during World War II. Her employment chances improved and she worked first in a food laboratory, then in a research laboratory. In the mid-1940s, she joined the Burroughs-Wellcome Company where she remained, working with Dr. George Hitchings until her retirement.
She had applied to fifteen graduate schools asking for aid so she could pursue her doctorate, and was turned down by all. Later she was to receive 25 honorary doctorates, including a Doctor of Science from the 51在线 (hon. causa) in June, 1993.
In 1991, she was the first woman to be inducted in the National Inventors Hall of Fame. The other 119 initially inducted included Thomas Edison, Alexander Graham Bell, and the Wright brothers. She also received the National Medal of Science, the Medal of Honor (American Cancer Society), and the ACS Garvan Medal.

Commencement Remarks
President Genshaft, Provost Wilcox, Board of Trustees, Faculty and Graduates. I have had, or shall I say, we all have had good fortunes to have had great teachers that pointed us in the right direction and that have always been there for us to fall back on when we needed them. It is their vision of the future for us whose "shoulder we stand on". Graduates, as you walk across this stage to accept your diploma, you will now have your opportunity to be that shoulder: A shoulder for all those younger than you. I came across a little story at the George Washington Carver Museum at Tuskegee University that summarizes this, and it goes as follows:
An old man, going on a lone highway,
Came, at the evening, cold and gray,
To a vast, and deep, and wide river,
Through which was flowing a sullen strea
The old man crossed in the twilight dim;
The sullen stream had no fears for him;
But he turned, when safe on the other side,
And started to build a bridge to span the river.
"Old man," said a fellow traveler,
"You are wasting strength with building here;
Your journey will end with the ending day;
You never again must pass this way;
You should retire, watch TV/movies, or go to the casino
Why build you this bridge ?"
The builder lifted his old gray head:
"Good friend, in the path I have come,"
"There follow after me today
A young person, whose feet must pass this way.
This river, has been naught to me,
To this young person this river may a pitfall.
This young one, too, must cross in the twilight dim;
Good friend, I am building the bridge for him
This honor, you bestow on me today, has given me a moment to reflect on all that I
have accomplished; and I realized that a significant part of my life has been devoted,
not only to doing research and research that I hope adds to improving and making life
on our planet Earth better for all, but part of my life's work has been to service;
and service to building bridges for our young people to enjoy successful careers in
our profession of chemistry. My choice of service to others has not been easy, but
it has been a wonderful and meaningful adventure. I have been lucky to have a wonderful
wife to share this adventure with me. Now sometimes you cannot always be a shoulder
for others to stand on, but at those moments, remember, you can be there to give people
a "box" to stand on that helps enrich their lives when given the opportunity. Congratulations
and good luck.

Commencement Remarks
It is customary on these occasions to offer what is thought to be a few words of wisdom to the graduates. First of all, I am reminded of one of the lines from Lincoln's Gettysburg address: "The world will little note nor long remember what we say here, but it can never forget what they did here." Your parents, relatives, and friends might be wondering: What did they do here? By virtue of the efforts of the graduates before us, in the last few short years the world around us has been transformed鈥攑erhaps imperceptibly鈥攂ut transformed nonetheless鈥攊n ways that we, or even they, may not yet fully comprehend. That is no small thing.
To the graduates鈥�
I have only a few words of advice for you: Don't leave!
Stay in touch with your university.
We are here today celebrating your accomplishments, hard-won by virtue of toil and dedication, forged in the crucible of frustration and ennui in the bowels of the lab or library. It bears remembering that your success is due in no small part to the acts of others: your parents, your relatives, your teachers, your friends and colleagues, random acts of kindness by strangers that provided that spark of an idea or a new perspective on a problem that challenged you.
I would hope that all of you leave here slightly singed by the fires of curiosity鈥攖hat sometime during your time here you will have experienced the exhilaration of a new discovery, the power of an untested but promising hypothesis, or the thrill in the pure majesty of an idea. Curiosity is an addictive drug鈥攐nce experienced, you want more. It is fuel that fires innovation鈥攁 glowing ember that when fanned with the passion of conviction and married to the discipline to confront the brutal reality of the limits of our current understanding鈥攜ou can illuminate the dark corners of our ignorance, and challenge the conventional, entrenched wisdom of how science or technology is practiced. Of all the human emotions, love is the most important and by finding something that you love鈥攂y throwing yourselves completely in it鈥攜ou will find great fulfillment in a life well lived.
Please do not forget that education and science is a social activity in which we constantly benefit from others鈥攚hose acts are not merely the product of their own self-interest. I know I am here because of the help from others, my teachers, my graduate students, my postdocs, and my friends at USF鈥攁nd of course my wonderful, supporting wife, Susan鈥攁nd to all them, please join me in giving thanks for this special day!
