Gary Leinweber Dec. 24, 1955 – Dec. 22, 2012 Resident of Fremont Gary Leinweber, 56, passed away peacefully in his home in Fremont on December 22nd after a long battle with cancer. First and foremost, Gary was a devoted and loving family man to son Johnny and wife Jerelyn, and to parents Jack and La Verne Leinweber of Newark. He is also survived by his loving brother, Ken, nieces Chrystal and Britney Leinweber of Fremont, and sister, LeeAnn (Randy) Plummer, of Nevada. Gary was born in Cleveland, Ohio, and moved to California with his family while in high school. He was a 1974 graduate and Valedictorian of Newark Memorial High School. Gary graduated in 1978 from U.C. Berkeley with a degree in Environmental Science. He was a member of the National Honors Society. After working in local industry, Gary accepted a position with the City of Mountain View Fire Department as a Hazardous Materials Specialist. He treasured his years working with the Mountain View Fire Department and the local community, working his way up to Environmental Safety Manager, and ultimately to Fire Marshal before his retirement in 2006. In 2000 he was awarded the prestigious 'Mountain View Fire Department Commendation Award'. Gary also treasured the time he spent volunteering with his son's Cub Scout dens and Mission San Jose Little League teams. A natural-born teacher, Gary decided to pursue his passion teaching high school mathematics, receiving a teaching credential from California State University, East Bay in 2008. Along the way, he volunteered at Mountain View High School and served an inspirational internship with the Mathematics Department at Logan High School. In Fall 2006 Gary began his teaching career with the Mathematics Department at Irvington High School, where he eventually taught Calculus, Pre-Calculus, Geometry, and Algebra. He relished his teaching experience, working alongside teachers, administrators, staff, and – most of all – his students. One of his favorite sayings was: 'Math is a SKILL, not a gift, so practice-practice-practice!' He particularly enjoyed applying real-world problems to his class assignments whenever appropriate, and he endeavored to make learning less stressful and more fun, while still mastering the material. Gary was honored when he was selected by N.U.M.M.I. as a recipient of its 2009 Most Promising New Teacher Award. An accomplished accordionist and singer, a major highlight of Gary's time with I.H.S. was participating in the 2008 musical, Footloose, performing the role of Reverend Shaw Moore. Remembering this experience always brought a smile to his face, as did memories of playing in a band with his brother Ken in the seventies. With wonderful support from Fremont Kaiser Oncology, Gary fought a long battle against cancer. Although he was a private man, he was thankful for the amazing support he received from family, friends, colleagues, and students. After cremation, burial will take place at a later date at the New Gottland Cemetery in McPherson, Kansas. In lieu of flowers, donations can be made to the Hayward Kaiser Hospice, 30116 Eigenbrodt Way, Union City, CA 94587.

Guestbook

  1. Gary Leinweber was quite a guy. He really enjoyed people. And his optimism in the face of his illness is most inspiring. He never gave in to his illness, he never gave up, he kept trying to beat it. And he tried very hard for a very long time. He had everything going for him but length of years. I am very disappointed by his loss. Courtney Hall

  2. Gary was such a wonderful guy. He was so kind and thoughtful, always such a positive outlook on everything. He died much too young. Our thoughts and prayer go out to Jerelyn and Johnny, and family. He will be missed. Rest in peace Gary. Ben, Jan & Tony Lenci

  3. Although I did not know Gary, I am newly married to his cousin Lawrence Leinweber in Ohio, the entire Leinweber family (Joe, Shirley, James, Larry, Greg and LInda) send their deepest sympathies and regret over you loss. After reading the obituary I can only imagine the wonderful person he must have been for so many.

  4. I knew Gary as a very capable and caring teacher and friend. He worked hard to help his students learn math, and I know they benefited from and appreciated his creativity. And what other teacher would take on a leading role in a school play, and excel in that too? He will be missed by all who knew him. Our thoughts and prayers are with his family.

  5. Our thoughts and prayers are with you, Jerelyn and John. We know Gary will be phenomenally missed as he made a difference in so many lives, not only when he was healthy but he continued to make time for others when he was sick. Gary gave to the world with a full heart and open hands. Gary made an incredible impact on our family. He was so patient with us, and encouraging – always. My son was blessed to have Gary as a coach and a math teacher. Gary taught him with clarity, compassion and character. With Gary, Ian was encouraged to believe in himself, work hard and help others in the classroom. Both the kids had Gary as a tutor when attending Mission and both kids felt he was one of the best teachers they ever had. Gary was a genuinely good man, sincere in his belief that the world is a good place and that those who live in it should be treated with patience and compassion. Thank you for sharing him with us. We will always remember him with joy.

  6. Gary, we often thought about you and prayed for you as well. Too bad we couldn’t have lived closer to each other. Rest in God’s love. Uncle Joe and Aunt Jean

  7. Gary Leinweber was one of my master teachers. He was gracious enough to let me teach his Calculus class for an entire week, although I had zero previous experience in teaching such a complicated subject. Gary was an inspiration to all his students; his humor, drama, and kidness kept his classes light-hearted and pleasurable. He was much loved by everyone at Irvington High School. I will always remember Gary and be grateful for the support and kindness he has shown me. I know that he is now in a better place, as he well deserves it.
