NEW YORK (AP) — Industrialist David H. Koch (kohk) and financier Henry R. Kravis have made separate donations totaling $250 million for hospitals and medical research in New York City.

The Wall Street Journal (http://on.wsj.com/1djZtEy ) reports Wednesday that Koch has given $150 million to Memorial Sloan Kettering Cancer Center.

His donation will help build a $1.3 billion, 23-story outpatient cancer center in Manhattan. It's expected to serve about 1,300 patients daily.

Koch has been a member of Memorial Sloan Kettering's board of overseers and managers since 1990.

The Kravis foundation is giving $100 million to Rockefeller University. It's building a laboratory research facility that will span three city blocks.

Kravis and his wife, Marie-Josee Kravis, say their gift will enable scientists to "push the boundaries of biomedical knowledge."
