Lester Halbert Germer (1896 – 1971) was an American physicist. With
Clinton Davisson, he proved the wave-particle dualityof matterin the Davisson-Germer experiment, which was important to the development of the electron microscope. He also studied thermionics, erosion of metals, and contact physics.
In 1945 (at the age of 49), Germer launched a side career as a rock climber. He climbed widely around the
Northeast United States, and especially at New York's Shawangunk Ridge. Although the Appalachian Mountain Clubwas dominant in the area at the time, and strictly regulated rock climbing, Lester was never associated with the club, and found himself in conflict with the leading climber in the area Hans Kraus, who was head of the AMC's Safety Committee. He was once turned down for climbing certification with the comment "Likes people too much and is too enthusiastic." Lester was known for being generous and friendly. He was once called "A one man climbing school."
In 1971, one week before his 75th birthday, Lester Germer died of a massive heart attack while
lead climbinga rock climb at the Shawangunk Ridge ("Eyebrow", 5.6). Until that moment, Lester had a twenty six year perfect safety record in rock climbing; he had never even taken a leader fall.
