Floyd Williams was raised in extreme poverty in Kansas City, Missouri and he had not thought of going to college until his last week in high school when he was offered a music scholarship at Lincoln University in Jefferson City, Missouri. He became side-tracked by Mathematics and Physics.
In 1962 Floyd L. Williams earned his B.S. in Mathematics from Lincoln University. At Washington University he earned his M.S.(1965) and Ph.D.(1972) in Mathematics. Dr. Floyd L. Williams held the positions of Associate Instructor at the University of California/Irvine (1970-72) and Instructor Massachusetts Institute of Technology (1972-75). At the University of Massachusetts-Amherst, Dr. Williams has been an Assistant Professor (1975-1978), Associate Professor (1978-84), and Professor (1984 -). In 1992 he was the Keynote Speaker at the Forum on Diversity, Excellence, and Motivation, Holyoke Community College. Dr. Williams has given piano recitals overseas. Details can be found on his vita page. Also see the autobiography the SUMMA web site. Also see the web page: Who are the greatest Black Mathematicians?
RESEARCH
Dr. Williams has given more than 65 invited lectures , colloquia, and seminar talks at 60 universities and institutes in 14 countries. Dr. Williams publication page for the complete list.
