John Francis Seymour Jr., the former United States Senator and Anaheim Mayor who became a pivotal figure in California's political evolution, died at his home in Carlsbad, California, on April 18, 2026, at the age of 88. While history records him as the last Republican to represent the Golden State in the Senate, his life was defined by a tenacious brand of moderate pragmatism that bridged the worlds of high-stakes real estate and public service.

Born in Chicago, Illinois, and educated in the public schools of Mt. Lebanon, Pennsylvania, Seymour forged his foundational discipline in the United States Marine Corps, serving from 1955 to 1959. This military rigor translated seamlessly into the private sector. After earning a Bachelor of Arts degree from the University of California, Los Angeles in 1962, he applied a builder's mindset to the business world. He founded Seymour Realty and Investment, achieving the status of a self-made millionaire by age 30, according to the Los Angeles Times. His industry leadership culminated in his tenure as President of the California Association of Realtors in 1980.

Seymour transitioned his deal-making acumen into local government, serving as the 39th Mayor of Anaheim from 1978 to 1982. During his mayoral tenure, he utilized his developer's perspective to negotiate the agreement that brought the Los Angeles Rams to Anaheim Stadium. His political ascent continued in the California State Senate, where he represented the 35th district from 1982 to 1991. In Sacramento, he exhibited an unexpected moderation that stood in stark contrast to the partisan polarization of later eras. He notably crossed traditional party lines to vote for bans on assault weapons and to outlaw discrimination against individuals with AIDS.

His pragmatic approach caught the attention of Governor Pete Wilson, who appointed Seymour to the United States Senate in 1991 to fill his own vacated seat, as reported by The New York Times. Stepping onto the national stage, Seymour experienced the immense pressure of federal governance. He observed, 'I felt like I was standing in the surf of a tidal wave, one wave after the other just crashing over my head and hardly being able to keep up.' Despite the overwhelming machinery of Washington, his resilience remained intact. Following his time in the Senate, he returned to his roots in housing and development.

Seymour served as the Director of the California Housing Finance Agency from 1993 to 1995 before finding a full-circle conclusion to his career. He took on the role of Chief Executive Officer for the nonprofit Southern California Housing Development Corporation, now known as National CORE, dedicating his final professional chapters to affordable housing. He is survived by his wife, Judy Seymour, and their six children: John, Lisa, Shad, Jeffrey, Sarena, and Barrett.

John Seymour approached governance not as an ideological battlefield, but as a construction site requiring blueprints, compromise, and a sturdy foundation. His legacy rests in his enduring belief that the mechanics of government should be used to build tangible solutions for everyday citizens, proving that a builder's pragmatism could successfully bridge the divide between private enterprise and public service.
