A scientist who never completed a university degree later became the first treasurer of a national scientific academy established in the 1950s. He was involved in research connected to nuclear tests and publicly challenged a government-appointed safety committee after concluding that radioactive fallout had reached a major Australian city. A controversial portrait of him, painted in 1953 by a prominent Australian artist, is now associated with an art gallery whose first permanent home opened on the south bank of a river in 1982. Tell me the exact date this scientist married.
