Fermilab employee Cheryl Bentham started at Fermilab on July 1, 1975, as a summer student. Four years later, she was offered a permanent position in the Housing Office, in September 1979. She has worked in the Housing Office since then. Now she is retiring. Her last day is Oct. 22.

Fermilab instrument welder Bill Gatfield started at the lab in March 1980. Since then, he has worked on numerous projects throughout the laboratory. Now, 40 years later, he is retiring. His last day is April 20.

For nearly 20 years, Tim Trout has supported all things construction at Fermilab. He started in 2000 as a contract worker. In 2007, he was hired as a full-time lab employee. Now he is retiring. His last day is Feb. 28.

On Feb. 19, Don Cossairt will retire after nearly 42 years at Fermilab. His work at Fermilab has included operational health physics as well as research in accelerator health physics and instrumentation, and he has contributed to the design and operation of nearly all Fermilab accelerators and experiments in the past four decades. Outside Fermilab, he has been a leader and worldwide expert in the field of accelerator health physics.

John Voirin, Fermilab ID number 04940N, has worked for Fermilab for just over 39 years, building magnets and installing numerous experiments. Now he retires. His last day is Feb. 12.

After an illustrious three-decade career as a particle physicist, Lynn Garren is retiring. Early in her career, she was involved with the E687, FOCUS and BTeV experiments. Since then, her work has been to provide software needed by Fermilab experiments. She supports the Class Library for High Energy Physics and is involved in a new effort to use Spack. She is also part of the SciSoft team and is the LArSoft release manager.

In the middle of the summer of 1976 a newly minted physicist came to Fermilab. No one could have guessed what his diverse interests, capabilities and perseverance would develop into at the laboratory. Peter Garbincius, a.k.a. “Peter G,” served in numerous leadership roles and served in multiple experiments during his time at the lab. He also organized the Ask-a-Scientist program to help Fermilab visitors understand the world-class science that goes on in their neighborhood.

TJ Gardner, badge ID 04569, arrived for work at Fermilab on Feb. 25, 1980, at the age of 19. Fermilab has been his entire career for nearly 40 years, and in that time, he worked on magnets for the Tevatron collider and project coordination for the Superconducting Magnet Group. Now he is retiring. His last working day is Thursday, Dec. 19, and he vows to remain “simply mah-velous.”
