William Sperber, the grandson of German immigrants, was born in Door County, Wisconsin, in 1941. He knew he wanted to be a scientist or a biologist from the time he was young. Raised by Lutheran farmers emerging from the Great Depression, he was fascinated by how grass grew and by how things worked. In 1959, when he enrolled in the UW’s College of Engineering, he did so with no financial support from his family. After a year, he transferred to the College of Letters and Science, where he received a bachelor’s degree with majors in zoology and chemistry. He earned a master’s degree and a PhD from the College of Agricultural and Life Sciences, then went on to a successful career as a microbiologist.
He has held positions at Best Foods, Pillsbury, and Cargill, where he retired in 2006 as senior corporate microbiologist. Today he continues to work on several major writing projects as a part-time Cargill employee and as secretariat for a new global initiative, the Safe Supply of Affordable Food Everywhere, Inc.
Renate Sperber was born in 1938 in Breslau, Germany. Her extended, freethinking family members became refugees after losing everything in World War II. She earned a business school degree in Sulingen, Germany, and emigrated to the United States in 1961. A successful office manager in Madison, she met William Sperber in 1963 at Rennebohm Drug Store, where they both worked part time to earn extra money.
