Bob Meistrell, who co-founded Body Glove, has died at the age of 84. Meistrell reportedly died from a heart attack Sunday while on his boat near Catalina Island.

Bob Meistrells motto was Do what you love, love what you do, Body Glove International President Russ Lesser said in an email to friends and business associates Sunday, according to a report in the Los Angeles Times.

Body Glove, which will celebrate its 60th anniversary this fall, was co-founded with Meistrell’s twin brother, Bill who died in 2006 at the age of 77. Both earn credit for helping develop in  the 1950s the first neoprene wetsuit, at the time using insulating material from the back of refrigerators.

Meistrell is survived by his wife, Patty, and three sons: Robbie, Ronnie and Randy.
