Howard Kerchak Duff, aka the first Howard K Duff, was born in 1852. His middle name was rather weird - because it means 'sculpin' in Russian - and unintentionally popular with Edgar Rice Burroughs, resulting in the avid real life fan naming his furry antagonist Kerchak himself!
He was also Edward Quartermaine's first surviving child. He and his younger brother George Louis Alke had a pretty good if estranged long term relationship with each other and their mother. He and George weren't big drunkards like the dad, who left their lives when they were kids.
A somehow controversial character, he was both a showman and a recurring bully as well, although he never slipped with women as much as his dad.
He and fellow co-founder Maisy Dell were married for a long time, due to a good relationship. They birthed their only child together, Howard Kerchak Duff JR, in 1890. They both died in a retirement home in 1934.
