SoBA mourns passing of former professor Siegfried Schaible

Schaible taught at UC Riverside from 1987 to 2006 and served as an Emeritus Professor of Management Science


The UC Riverside School of Business Administration lost one of its valued former faculty members in early September with the passing of Siegfried Schaible, an Emeritus Professor of Management Science, at the age of 74. He was a long-time professor for the A. Gary Anderson Graduate School of Management.

Professor Schaible was born in Marburg, Germany during World War II. After graduating from high school, he attended the University of Mainz, where he met his future wife, Ingrid. They were married in 1967. He went on to study mathematics and physics and to earn two doctorates from the University of Cologne.

In 1979, he and his family immigrated to Canada, where he taught at the University of Alberta in Edmonton. In 1987, he became a tenured professor at UC Riverside, teaching at the Anderson School until his retirement in 2006. He then moved to Taiwan, where he taught at Chung Yuan Christian University.

"He was a true scholar, thoughtful, wise and very respectful to his colleagues,” SoBA Professor of Operations and Supply Chain Management Mohsen El Hafsi said. “Professor Schaible’s research made great impact in several fields, starting with his early work on Fractional Programming and ending with his work on Generalized Convexity. Throughout his career, his work has generated over 6,900 citations. Professor Schaible was one of the few, in the University of California, to be elected AAAS-Fellow of the American Association for the Advancement of Science, in 1998.”

Schaible wrote and edited a number of scientific journals and books in his area of expertise, generalized convexity. During his spare time, he enjoyed reading theology, taking pictures, playing the violin and exploring the outdoors.

He was a widower for the past 11 years. He is survived by his siblings in Germany, Dieter Schaible and Waltraut Kippenberger; his daughter and son-in-law, Sue and Frank Suranyi of Camarillo; his son and daughter-in-law, John and Christy Schaible of Santa Ana; his daughter Rickie Schaible of Poway; and, his seven grandchildren.
