Marine industry veteran Larry Johnson, founder of EZ Loader Boat Trailers, died May 6 in Spokane, Wash. He was 97.
Johnson started EZ Loader in 1953 and built it into the largest boat trailer manufacturer in the country, the company said in a statement.
In the mid-1960s he patented the "All Roller Trailer." Trailers previously had bunks or a combination of bunks and rollers.
EZ Loader is still managed and owned by the Johnson family. Larry Johnson's son, Randy, serves as president.
"Larry touched the lives of many and will be missed greatly," the company said.
Funeral arrangements were not immediately available.
