James Tosh, known to friends and family as Jim, passed away on January 23, 2024, at the age of 76. Born on August 14, 1947, Jim lived a fulfilling life of joy and accomplishment.

Jim was a loving son to Shelby and Betty Tosh and a protective brother to siblings Robert (Bobby) Tosh, Teri Taft, Janet Lundgren, and Julie Scott.

He is survived by his beloved sons, James (Jim) K Tosh, Christopher Tosh, and John Tosh. The memories they shared with their father will forever hold a place in their hearts. James also leaves behind his caring daughters-in-law Deanna Tosh and Emily Tosh, his loving partner Lucy Taylor, and the mother of his 3 sons Willie Tosh.

A devoted grandfather, Jim had four cherished grandchildren: Tyler Tosh, Ashley Tosh, Bowie Tosh, and Harrison Tosh. His love for them knew no bounds, and his brightest smiles came during times spent together.

Jim will be remembered not only for his roles as a son, brother, father, and grandfather but also for the impact he made on those around him. He possessed an unwavering kindness that left an indelible mark on the lives he touched.

In addition to being a guiding light for family and an expert woodworking craftsman, Jim had a strong passion for golf. His skill on the course was matched only by his enthusiasm for the game. He was often found perfecting his swing at various golf courses and in his backyard.

After colorblindness kept him out of the Navy's nuclear submarine program, he spent 4 years on the USS Dixie working in the machine shop repairing ships in the Pacific Fleet. After his time in the Navy, Jim returned to the San Fernando Valley and had a storied career in the Aerospace industry. 

Jim dedicated more than 4 decades to enabling national defense systems and the exploration of space. He started in the machine shop and rose through the leadership ranks, working on missiles, ICBMs, rocket engines, landing craft, and energy systems. He was proud to be part of the team that designed, built, and delivered the Space Shuttle Main Engine (SSME), specifically the fuel system turbo boosters. He was integral in delivering the mars rover power source by solving a manufacturing process allowing the nuclear power supply to be built.

His know-how was then translated into building some of the largest solar arrays in the world. His knowledge and understanding of how to take something from design to production was unmatched. His sons always consulted with him prior to building anything. He will be missed within the space engineering world as well as at home.

To honor Jim's life and celebrate his many accomplishments, a Celebration of Life gathering will take place on March 17, 2024. Family and friends are invited to join together at the Tierra Rejada Country Club in Moorpark, CA (15187 Tierra Rejada Rd.) to reminisce about the moments they shared with him. The gathering will begin at 2:30 PM and be followed by an appetizer reception. An RSVP is appreciated, but most important to his family is your attendance. Please share this info with anyone who knew Jim.

Jim's departure has left a void in the lives of those who loved him. However, his memory will be preserved through the stories, laughter, and love that he shared with his family and friends. May he find eternal peace as we carry his spirit with us.

In lieu of flowers, trees, or any other gifts, please help Jim's family celebrate his life by sharing any photos you have with Jim and your favorite memories, fun stories, work accomplishments, or anything else the family would enjoy below.
