Who was Leonard John Brass?

Leonard John Brass was an Australian and American botanist, botanical collector and explorer. He was born at Toowoomba, Queensland. He was trained at the Queensland Herbarium, which he collected plant specimens for from the 1930s to the 1960s, as well as participating in several international expeditions to New Guinea, the Solomon Islands and Africa.

From 1939 to 1966 Brass was an associate curator of the Archbold Expedition collections with the American Museum of Natural History. He was associated with the Archbold Biological Station at Lake Placid, Florida, for which he helped to formulate the organizational structure it has today, and also where he lived between expeditions. In the course of his many expeditions to New Guinea he was a major collector of plant specimens for the Arnold Arboretum in Massachusetts. He was especially interested in the relationship between the floras of Australia and New Guinea.

Brass was director of field operations for an expedition in 1949–50 to tropical Africa, sponsored by the Upjohn and Penick companies, to find precursors for the manufacture of cortisone.
