Bill Clements, a former Texas governor, has pledged $100-million to the University of Texas Southwestern Medical Center and has placed no restrictions on the gift, reports The Dallas Morning News.

Mr. Clements, who is 92, said in a written statement that he hopes the university can use his donation to attract other donors.

Bill Solomon, chairman of the Southwestern Medical Foundation, said the gift comes at just the right time since donations to the foundation have fallen off both because of the recession and because many donors gave during the institution’s $773-million fund-raising campaign, which ended in 2007.

Mr. Clements’s $100-million pledge — the second such pledge announced in the last four weeks — will be paid out over four years, said Mr. Solomon.

It follows a $100-million pledge to Habitat for Humanity International from J. Ronald Terwilliger, chairman of Trammell Crow Residential, a Dallas real-estate company. (See the Chronicle’s searchable database of information about big gifts.)
