Jeff Vadasz Obituary

Published by Legacy Remembers on Sep. 18, 2025.
Jeffrey "Jeff" Vadasz, 60, passed away on September 3, 2025, in Los Altos, California. A devoted husband, accomplished engineer, and passionate enthusiast, Jeff leaves behind a legacy of innovation, laughter, and love.

Born August 12, 1965, Jeff grew up in Los Altos, California. He graduated from Awalt High School in 1983 and Oregon State University in 1988. Jeff's professional highlight was at Broadcom, where he played a part in the development of 802.11 Wi-Fi technologies-advancements that continue to shape how people connect across the globe. His colleagues knew him not only for his technical accomplishments but also for his leadership, enthusiasm and collaborative spirit.

Outside of work, Jeff found joy and inspiration through travel, cycling and landscape photography. These were not solitary pursuits for him; they were avenues for camaraderie, shared adventure and creativity. Whether conquering one of his many endurance rides or capturing the perfect shot, his joy came as much in the shared experience as in realization of his goals. Those who knew him will remember his warmth, infectious smile and quick wit-he loved to laugh and delighted in making others laugh along with him.

Jeff faced Corticobasal Syndrome and Alzheimer's disease with courage and resilience. Jeff was grateful to all who supported him during the last few years - his medical team, caregivers, devoted friends, and, especially, his loving family.

He is survived by his beloved wife Diane Schmidt; his parents Leslie and Judy Vadasz; his brother Dave Vadasz and sister-in-law Yoshiko Nishimura; nephew James Vadasz; and niece Katie Vadasz. He was preceded in death by his grandparents Gail and Sally Young and Gyula and Maria Vadasz.

In lieu of flowers, the family requests that donations may be made in Jeff's memory to CurePSP (www.psp.org) to help fund research into neurodegenerative diseases. A celebration of Jeff's life will be scheduled at a future time so that friends and family may gather to honor his memory.
