Nathan Tushinsky; Former Marantz Executive

Nathan Tushinsky, one of four brothers who formed a company called Superscope, which developed an early wide-screen projection process, has died in Sherman Oaks. He was 76.

A longtime resident of Encino, Tushinsky died Friday of complications of Parkinson’s disease, said his daughter, Kathleen Tushinsky.

Tushinsky and his three brothers formed the Superscope company in Sun Valley in 1954, and in 1957, the company became the first distributor of Sony tape recorders in the Western Hemisphere. The brothers purchased the Marantz Co. in 1962, and four years later, the company became publicly traded. Tushinsky served as executive vice president until he retired in 1977. The company was later sold to Dynascan Corp.

In 1976, the City of Hope honored the brothers with its Humanitarian Award.

Tushinsky is survived by his daughters, Jacqueline Tushinsky of San Diego and Kathleen Tushinsky of Encino; a brother, Fred Tushinsky of Encino, and a sister, Lillian Goldman of Encino.

A funeral service was held Sunday, with burial at Mt. Sinai Memorial Park in Los Angeles. Glasband-Willen North Hollywood Mortuary handled the arrangements. Donations can be made to the American Parkinson’s Assn.
