The Father of Soviet Physics, Abram Fedorovich Loffe was the Russian physicist and the founder of many physics institutes in Russia. He was born on October 29, 1880, in a Jewish family in the small town of Romney, Russian Empire. Abram carried out experiments on elastic and photoelectric properties of crystals and was the first scientist to be fully credited for discovering the charge of an electron for which he received the Nobel Prize in Physics. Abram was given the nickname “The Red Professor” and he founded the State Roentgenologic and Radiological Institute and was the head of Physics and Technology faculty. Abram proved the quantum nature of light and also discovered the ionic nature of crystals. He introduced new ideas about semiconductors and was given the nickname “Father of Semiconductors”. Abram was an expert in the field of physics and electromagnetism and was awarded the Stalin Prize in 1942, the Lenin Prize in 1960, and The Hero of Socialist Labor. Take this quiz about Abram Ioffe.
