Pyotr Ufimtsev

Pyotr Yakovlevich Ufimtsev (Russian: Пётр Я́ковлевич Уфи́мцев) (born 1931 in Ust-Charyshskaya Pristan, West Siberian Krai, now Altai Krai) is a Soviet/Russian physicist and mathematician, considered the seminal force behind modern stealth aircraft technology. In the 1960s he began developing equations for predicting the reflection of electromagnetic waves from simple two-dimensional shapes.

Much of Ufimtsev's work was translated into English, and in the 1970s American Lockheed engineers began to expand upon some of his theories to create the concept of aircraft with reduced radar signatures.

Ufimtsev was born into a peasant family in the village of Ust-Charysh Pristan (N 52.40, E 83.66), in the Altai region, of the RSFSR of the former USSR. At the age of 3 his father was repressed by the regime and later died in a forced labor camp (GULAG system). In 1949 Ufimtsev finished school and entered the physics-math department at Almaty State University (now in Kazakhstan). Because of progressing myopia (nearsightedness) he had to move from Almaty to a specialized clinic located in Odessa, Ukrainian SSR. Later in 1952 he continued his studies at the Odessa State University. After graduating from university in 1954 he was invited to attend the Institute of Radio-engineering and Electronics in Moscow, where he specialized in electronic warfare.
