He was a longtime member of the Oakmont Country Club and held season tickets for the Dodgers' inaugural year in Los Angeles, his son, Denis Wolcott, said.
"You can't get much more L.A. than that," he said.
Wolcott — who among others was credited with being at the forefront of developing the modern concept of public relations — assembled a long list of corporate clients that spanned the globe, including MGM, Voit Rubber Co., the American Dairy Assn., Western International Hotels, MCA/Universal Studios and the Metropolitan Authority of Los Angeles.
"We've been receiving calls from all around the world from his friends and business associates," Denis Wolcott said.
Over the course of this career, Wolcott merged his firm with international public relations firm Burson-Marsteller before leaving to start his own executive counseling firm.
Wolcott served as the president of the Public Relations Society of America in 1966 and served for more than 20 years as a UCLA Medical Center Board member.
He also formed the Public Service Council of the Public Relations Society of America and the Consultants Group of the International Public Relations Assn.
Wolcott is survived by his sister, Helen Bagley; wife, Sharyle L. Sponsler; daughter, Robin Fayette; sons Denis and Steve Wolcott; seven grandchildren; a niece and two nephews.
A public memorial service will be held at 1 p.m. on Sunday, July 8, at the Reef Restaurant, 880 S. Harbor Scenic Drive, Long Beach.
In lieu of flowers, donations may be made to the Ruth Denas Wolcott Endowed Scholarship in Music Performance at UCLA's Department of Music, named after Wolcott's first wife.
