After divorcing Lucille Ball in 1960, Desi Arnaz moved into their Del Mar summer home at 1920 Ocean Front Drive. They worked together again on the Lucy Show in 1962, but only for eight episodes. The next year, he married his second wife Edith Mack Hirsch.
He produced and appeared in the TV show Mothers In Law from 1966 through 1967, later donating his show archive to SDSU (where Desi Arnaz Jr. attended in the early 1970s).
Arnaz died in Del Mar on December 2, 1986. He was cremated at the Cypress View Crematory on Imperial Avenue.
