St. Louisan who won Nobel Prize dies at 95

ST. LOUIS -- William S. Knowles, a chemist at Monsanto Co. in St. Louis who shared the Nobel Prize at age 84 in 2001, has died.

Knowles, of the St. Louis suburb of Chesterfield, Mo., died June 13. His daughter, Lesley McIntire of Kirkwood, Mo., says he died of complications from ALS.

Knowles retired from Monsanto in 1986 after 44 years with the company. But it was 15 years later that he and two other scientists won the Nobel Prize in chemistry for work that led to discoveries now used to make various medicines, including antibiotics, heart drugs and widely used treatment for Parkinson’s disease.

His body was cremated. A memorial service will be at 2 p.m. June 30 at Episcopal Church of the Good Shepherd in suburban St. Louis.
