Kellermann (sometimes recorded as "Kellerman") was born in Marrickville, New South Wales, Australia, on 6 July 1887,[REF] to Australian-born violinist Frederick William Kellermann, and his French wife, Alice Ellen Charbonnet, a pianist and music teacher [REF].
At the age of six, a weakness in Kellerman's legs necessitated the wearing of steel braces to strengthen them.
