Frederick and his wife, Rhoda, came to be informally known as the King and Queen of Malibu,[1] and with an estimated net worth in the millions of dollars,[2] the family was considered one of the wealthiest in the US.

[10][11] He grew up in the "Rindge mansion", still standing at the corner of Dana and Harvard Streets in Cambridge, but spent vast swathes of his childhood very ill, condemned to bed with swollen joints, body spasms, a wildly irregular heartbeat, and other ailments.

[12] Bible stories were of some solace to him, with "tales of men defeating long odds because God was on their side" rooting him in faith and religion from a young age.

He was so severely ill that his doctor suggested he might find a better chance of survival if he sought out a warmer climate than Massachusetts could offer, which led him to St. Augustine, Florida.

His investments included land near Stockton, California and real estate holdings in the San Fernando Valley of Los Angeles, and the state of Sinaloa, Mexico.

He was President of the Harvard Club of Los Angeles and a member of many historical, archaeological, patriotic, and religious organizations which mirrored his interests.

They moved to Wilshire and Ocean Avenue in Santa Monica and then built a home at 2263 Harvard Boulevard in Los Angeles, known today as the Frederick Hastings Rindge House; weekends and summers were spent at their Malibu estate.

[21] He and his wife, May, first stayed in a small cabin on it that had been built by one of the ranch's previous owners, Matthew Keller, naming it Oak Cottage.
