In Loving Memory of John Alexander Despotakis

It is with profound sadness that we announce the passing of John Alexander Despotakis on February 15, 2026.

Born on September 9, 1936, in San Francisco, California, John lived a life defined by devotion, integrity, and unwavering love for his family. He was preceded in death by his beloved wife of 69 years, Peggy, and his oldest son, Paul. He leaves behind a legacy cherished by their remaining five children, seven grandchildren, and four great-grandchildren.

A proud graduate of Washington High School, John continued his academic journey at City College of San Francisco and UC Berkeley. John met Peggy, the love of his life, while he was attending City College of San Francisco. They married on Peggy’s 20th birthday—January 13, 1956—beginning nearly seven decades of partnership, adventure, and enduring devotion. Their Christian faith was a cornerstone of their relationship.

During John’s service in the United States Marine Corps, he and Peggy lived throughout the country before ultimately returning to the Bay Area. They built their home first in Pleasanton and Danville, later settling in Livermore, where they lived for the past 25 years.

Professionally, John made a lasting impact in the technology industry, working first with Daconics, then joining Tandem Computers as Employee #13 and contributing significantly throughout his career. An inventive and dedicated problem-solver, he earned 13 patents, a testament to his brilliance and drive.

John will be remembered for his warmth, strength, and steadfast love—qualities that shaped the lives of everyone who had the privilege of knowing him.

Please join us as we gather to honor and celebrate John’s life.
