[3] Anton was born in Ostrog, Russia,[3] (perhaps Ostrog, Šentjernej) and in 1912 left as a refugee for Australia, and founded a radiator repair and sheet metal fabrication shop "King & Katts"[4] at 623 Wickham Street, Fortitude Valley, Queensland.
[a] Both parents were musicians: Anton played balalaika and mandolin; Lucretia was a pianist, and Katts had private piano tuition, initially with Constance Hartshorn, organist for the Enoggera Presbyterian church,[6] then from around 1930 with John Ellis, who took out a newspaper advertisement when Kitts graduated ATCL and LTCL in 1939.
[7] Katts married John Stanton Davis Mellick (born 22 February 1920),[8] on 8 December 1941.
This collection documents the creative life of the Queensland composer and comprises compositions, arrangements, correspondence, certificates, newspaper clippings, personal items, video and sound recordings.
[22] The biennial Letty Katts Fellowship was established by Stan Mellick in 2016 to support research into Queensland's music history, and consists of a stipend of $5,000 plus twelve months' access to the Neil Roberts Research Lounge at the State Library of Queensland and documents held by the Library.
