Richard Pratt, a Polish emigre who became one of Australia’s richest men and a leading international patron for Jewish causes, died of cancer Tuesday at age 74, the Jewish Telegraphic Agency reports.

Mr. Pratt, who immigrated to Australia with his parents on the eve of World War II, made his estimated $3.8-billion fortune as the head of Visy Industries, a global packaging and recycling business. The Pratt Foundation, which he founded in 1978 with his wife, Jeanne, has given some $140-million to charities in Australia, Israel, and the United States.
