ALBANY, N.Y. (AP) _ Bernard Vonnegut, a chemist known for discovering cloud-seeding techniques and for being novelist Kurt Vonnegut Jr.’s older brother, died Friday. He was 82.

In 1946, while working at the General Electric Research Laboratory in Schenectady, Vonnegut discovered the power of silver iodide as a cloud-seeding agent. For the last four decades, his work focused on how lightning gets started. No generally accepted theory currently exists.

He held over two dozen patents and published prolifically, frequently listing students as co-authors. He worked at GE and Arthur D. Little in Cambridge, Mass., before joining the faculty at the State University of New York at Albany in 1967.

He retired in 1985 but continued his research.

Born in Indianapolis, Vonnegut earned his bachelor’s degree and doctorate at the Massachusetts Institute of Technology.

His brother has frequently mentioned him in his writings.
