Camden Morning Courier – July 8, 1904
The Casson Brothers, a clever acrobatic team, have secured an engagement at Guvernator’s pavillion theatre, Atlantic City, the last week in July. The team is made of Vincent Tydeman and William Dool, two local boys, Casson Brothers is their stage name [I assume this later became Tydeman and Dooley. –ed.]. Last season they did a turn at Electric Park and the management was much pleased. One of their dexterous acts consists of marvelous hand-to-hand balancing. Their work is refined and thoroughly up to date.
