William H. Tansky Jr. was a WWI veteran who by 1930 was operating a cafe at 1903 South 6th Street in Camden NJ. Tansky was active in Republican politics in Camden's 8th Ward. On May 16, 1934 there was a near-riot at Tansky's cafe over the results of the bitterly contested 1934 primary, where control of the Republican Party in Camden County  was fought over by David Baird Jr. and Albert S. Woodruff. 

By 1946 William H. Tansky was no longer involved with the bar. Dominick Kasilowski and his family resided at 1903 South 6th Street, and operated the bar as Dominik's Cafe. Son Adam Kasilowski, who still lived at home, also worked there, as a bartender. 

Dominick Kasilowski was a native of Poland. After moving from 1903 South 6th Street, he lived for many years at 1355 Jackson Street in Camden. He passed away sometime after 1959. His wife Frances was still residing there as late as 1970. Besides his wife, Dominick Kasilowski left a daughter, Mary, and a son, Adam.
