He continued his work on natural product chemistry at Lederle Laboratories in Pearl River, NY from 1958-1967 where he rose to group leader in antibiotic discovery. In 1967, he accepted an associate professorship in Natural Products Chemistry at The Ohio State University to pursue his passion for teaching, quickly rising soon to the position of Tenured Professor. In 1975, he joined University of Kansas as a University Distinguished Professorship and the Chairmanship of the Department of Medicinal Chemistry. He returned to the faculty in 1992 and retired as Emeritus Professor in 2011. During his tenure, he also held conjoint academic appointments at the University of Missouri – Kansas City and the Victorian College of Pharmacy, Melbourne, Australia.

Throughout his decorated career, he earned numerous awards and honors. These included the Research Achievement Award in Natural Products Chemistry from the American Pharmaceutical Association (1980), the Ernest H. Vorweiler Award for Research Achievement from the American Association of Colleges of Pharmacy (1985), the Higuchi-Simons Award in Biomedical Sciences at Kansas University (1986), the Bristol-Myers Squibb/Edward E. Smissman Award in Medicinal Chemistry from the American Chemical Society (1989), Fellow of the American Association for the Advancement of Science (1995), the Division of Medicinal Chemistry Award from the American Chemical Society (2000), and the Norman R. Farnsworth Research Achievement Award from the American Society for Pharmacognosy (2007).

Dr. Mitscher’s research focused on the isolation, identification, and optimization of naturally occurring antimicrobial and anti-cancer agents, as well as the development of combinatorial methodologies. He published more than 270 research publications and authored or co-authored seven technical books on drug discovery and properties. He was on the editorial board of several technical journals including the Journal of Medicinal Chemistry and the Journal of Natural Products. He also consulted widely among pharmaceutical firms, serving as senior advisory council member of firms such as Abbott Laboratories, Searle Laboratories, Dupont-Merck, among others.

Visitation will be held at Rumsey-Yost Funeral Home from 6-8 pm on Thursday, May 14th, 2015. Services will be held at Plymouth Congregational Church, Lawrence, KS, on Friday May 15th at 3 pm.

Dear Betty,
We are very saddened to hear this news. He taught me so much and I deeply miss him. I used to go and talk to him whenever I had a problem. He makes me forget all that after few minutes of talking to him. He is very unique and amazing human being. I feel blessed to have worked with him and known him for a long time. My deepest sympathy to you and your family.

Dear Mitscher Family,

From Pratik Devasthale...

Dear Betty,

We are very sorry to hear the sad news. Les Mitscher was an extraordinary human being, scientist, speaker, and a mentor with a great sense of humor. I still fondly recall, during my (below minimum wage-paying) grad studies, when he noticed that I wore a new shirt to the lab, he immediately quipped, “I am obviously paying you too much!” and followed it with his characteristic infectious laugh. As my graduate advisor, I am forever indebted to him for caringly shaping my life & career in the US in so many positive ways.

With deepest sympathies and prayers for you and your family,

Pratik and Madhavi

From Anthony C. Bonacci...

Dear Betty and family,
We send our deepest sympathy on the sudden passing of a great man. Les was my principal advisor for my graduate work (1967-1969) at O.S.U. He was like an older brother to me, guiding me through our ORD-CD work on the tetracycline antibiotics. I will remember him as a cheerful, neat and meticulous gentleman with georgous handwriting! We cherish the yearly Christmas cards and handwritten updates on your family and travels. Love and peace to you all.
Fondly, Tony & Elaine

From Tom Patton...

Betty and family, My sympathies on Les’s passing. How as a great colleague and a world class scientist. His legacy will live on.

From james and madelyn visconti...

dear betty, madelyn and I were saddened tohear of Les’s passing. I remember many times talking with Les about his antibiotic work, pharmacy,chemistry and other topics like the politics of the university, the dean and many funny aspects of the campus and columbus. I’ll always remember when we went to Cleveland to give lectures to the local pharmacy group. It was early sunday morning and the car broke dowm in some small town in Ohio. It was freezing and we had no heat in the car. Finally help arrived and rescued us. Les was always willing to hear my questions on medicinal chemistry and willing to discuss them which often lead to other questions. I will always have good memories of Les and his harty laugh, a good colleague and as a serious and outgoing college professor. You, Les and your family are in our prayers. Jim and Madelyn Visconti

From Nancy Wood, Hafrsfjord, Norway...

I received a very kind letter from Dr. Mitscher back in 1991, when I was serving in the Peace Corps. (I had read about his research on taxol. His work made world news.) I was recovering from serious illness at the time, so I wrote a letter, thanking him for his important research. To my surprise, he took time out of his very busy schedule to reply. That letter I have saved all these years. He was very gracious and humble, I recall. May Dr. Mitscher’s memory be a blessing.

From Binghe Wang...

Dear Betty,
We are both very much saddened by the news of Dr. Mitscher’s sudden death. As students of the Med Chem department, we both benefited enormously not only from his chemistry knowledge and his teachings, but also his generous personal help. We regard him as a kind and compassionate teacher and a personal friend. Our deepest sympathy to you and your family.

From Tom Perun...

Dear Betty,
I was very sad to hear about Les’ passing, and was looking forward to seeing you and him again later this month in Illinois. I consider myself to be fortunate to have known him for 50 years as a research collaborator, consultant and dear friend. I will always have fond memories.

From Elaine Darst...

Dear Betty,
Les and you together have been such good friends and mentors to so many, who will miss him deeply, and who care very much about you. I am so sorry about his death, and send my deepest sympathy.
