Former AIChE President Leaves Legacy with Foundation Bequest

April 12, 2013

The AIChE Foundation shows its appreciation for the generosity and foresight of people who have arranged for long-term financial support of the Institute by inducting these donors into the Foundation’s Legacy Society.

One recent Legacy Society inductee is the late Klaus Timmerhaus, AIChE’s president in 1976 and a Fellow of the Institute. Timmerhaus, who died in Feb. 2011, made a bequest of $100,000 to the AIChE Foundation, along with a request that the funds be allocated to AIChE’s Unrestricted General Fund — which supports a range of vital programs such as AIChE’s global outreach efforts, government and public education initiatives, undergraduate curriculum reform efforts, and activities to engage young engineering professionals in AIChE leadership.

A longtime member of AIChE, Timmerhaus spent 43 years on the chemical engineering faculty at the Univ. of Colorado, Boulder (CU), where he became a full professor in 1961. During his time at CU, he served as associate dean of engineering, director of the Engineering Research Center, and chair of the chemical engineering department.

Timmerhaus is well known for his textbook, Plant Design and Economics for Chemical Engineers (written with Max Peters). He contributed extensively to the field of cryogenics; he served as founding editor of the journal Advances in Cryogenic Engineering, which he edited from 1954 to 1980. A member of the National Academy of Engineering, Timmerhaus received many teaching and research honors. Within AIChE, he received the Alpha Chi Sigma Award for Chemical Engineering Research; the Founders Award for Contributions to the Field of Chemical Engineering; the Warren K. Lewis Award for the Chemical Engineering Education; and the F. J. and Dorothy Van Antwerpen Award for Service to the Institute. In 2008, AIChE named Timmerhaus one of the 100 Chemical Engineers of the Modern Era, recognizing his contributions to cryogenics science and practice.

Donations of any amount can be made to the AIChE Foundation to support the projects and activities that further the Institute’s mission and strengthen its role as global leader of the chemical engineering profession.

The AIChE Legacy Society was established in 2007 to honor those who have included AIChE in their long-term plans through a bequest provision, life-­income gift, or other deferred giving arrangement. Through such generous arrangements that name AIChE a beneficiary of an estate plan, Legacy Society members achieve their own financial goals while leaving a legacy for the future of the Institute.
