Professor Emeritus Caspar Curjel died on October 15, 2017, in Zurich, Switzerland. Caspar was born in Berlin but grew up in Zurich, where he studied at the Eidgenössische Technische Hochschule, receiving his doctorate in 1960. He spent two years at Cornell and two years at the Institute for Advanced Study in Princeton before coming to UW, first for a year as a visiting faculty member, then from 1965 onwards as a regular member of the faculty. In addition to research in algebraic topology and superb teaching, Caspar contributed invaluable service to the department and the university, including directorship of the department’s undergraduate program. He retired in 1998 and continued teaching for a short time after, ultimately returning to Zurich with his wife, Marianne, for the remainder of his life.
