Julian "Tex" Robertson (April 23, 1909 – August 27, 2007) was an American swimmer and water polo player and a swimming coach for the University of Texas.

Between 1934 and 1935 Tex set new collegiate and Amateur Athletic Union records while continuing to win individual and team events for the University of Michigan.

He brought attention to the UT swim team by recruiting incredible swimmers that ended up going to the Olympics.

For thirty years that swimming pool hosted Burnet's small high school state championships.

He shut the camp down for three years when World War II broke out so he could join the United States Navy, where he trained Underwater Demolition Teams[8] and survival swimming skills.

He was stationed in San Diego and then transferred to Fort Pierce, FL where he taught the Underwater Demolition Teams.

Many popular camp objects were inspired from World War II including a Vietnam-era, 40-foot long gasoline storage tank that was inflated and children jumped onto it while another flew off, along with ice cream lids children threw back and forth eventually becoming the Frisbee.

Vic Malfronte, the World Frisbee champion, gives credit to Tex for creating the earliest organized sailing disc games.

The first year Camp Longhorn opened it only had one camper and sixteen counselors all swimmers from the University of Texas.
