Erlanger is a very deep lunar impact crater that lies near the north pole of the Moon. Due to its position near the lunar north pole (and given that the Moon's axis is only tilted about 1.5°), sunlight only rarely falls on the bottom, and the 2008 Chandrayaan-1 probe hoped to find that ice from comet impacts had accumulated there. Erlanger is one of the Moon's permanently shadowed craters.

Together with Herbert Spencer Gasser, he identified several varieties of nerve fiber and established the relationship between action potential velocity and fiber diameter. They were awarded the Nobel Prize in Physiology or Medicine in 1944 for these achievements. Biography Erlanger was born on January 5, 1874, at San Francisco, California. His family was Jewish and his parents both immigrated from the Kingdom of Württemberg, Germany and met in California during the Gold Rush. Joseph was the sixth of seven children born to the couple. He completed his Bachelor of Science in Chemistry from the University of California, Berkeley in 1895. He then completed his M.D. in 1899 from the Johns Hopkins School of Medicine in Baltimore, Maryland, where he finished second in his class. Upon graduating, Erlanger interned at Johns Hopkins Hos ...
