Detroit-area developer and philanthropist A. Alfred Taubman today pledged to give $11 million to Lawrence Technological University for an engineering, architecture and life sciences building in his name.

The donation brings to about $225 million the amount of money Taubman has given to universities, art schools and institutes and other causes.

Last month, he donated $56 million to the University of Michigan for stem-cell medical research. Taubman has given $142 million to U-M, of which $100 million went to the A. Alfred Taubman Medical Research Institute.

Asked what motivates the giving, he quipped. “I’m 87 years old. Gotta give it away some time.”

With a net worth of $2.3 billion, Taubman is the fourth richest man in Michigan and ranks 512th among 1,210 listed this year on Forbes magazine’s World’s Billionaires list.

Taubman, who did not complete college, studied at the University of Michigan for three years before transferring to night school at Lawrence Tech as a junior. He took classes at night for two years when the school, now in Southfield, held classes in Highland Park. In the last year, he returned to teach at the school, though he joked that his title as affiliate professor of architecture and design came without faculty parking privileges.
