Aleksandr Stepanovich Popov

Japanese: ポポフ - ぽぽふ(英語表記)Александр Степанович Попов/Aleksandr Stepanovich Popov
Aleksandr Stepanovich Popov

Russian radio researcher. Born in a mining village in the Ural Mountains as the son of a pastor. He graduated from St. Petersburg University in 1883, and after working as an assistant in the university's physics laboratory, he became an instructor at the Kronstadt Torpedo School. Inspired by the research on electromagnetic waves and detectors by Hertz, Branly, and Lodge, he improved receiving circuits such as antenna devices and the detector (coherer) invented by Lodge, and performed the first public experiment at the Russian Physical and Chemical Society in St. Petersburg on May 7, 1895. The following year, 1896, independently of Popov, an Italian man named Marconi obtained the first patent for wireless telegraphy. Inspired by this news, Popov built the first radio station in the same year in collaboration with the Russian Navy, and in 1899 rescued the stranded warship Apraksin. However, unlike Marconi, Popov's work was not recognized, and he returned to professorship at St. Petersburg University in 1901, and was elected director of the university's Institute of Electrical Engineering in 1905.

ロシアの無線研究者。ウラル山系の鉱山村に牧師の子として生まれる。1883年ペテルブルグ大学を卒業し、同大学物理実験室助手を経てクロンシュタット水雷学校教官となる。ヘルツ、ブランリー、ロッジの電磁波と検波器に関する研究に刺激され、アンテナ装置やロッジの発明した検波器(コヒーラー)など受信回路の改良を行い、1895年5月7日サンクト・ペテルブルグのロシア物理・化学会で最初の公開実験を行った。翌1896年ポポフとは独立にイタリアのマルコーニが無線電信に関する最初の特許を得た。このニュースに刺激され、ポポフは同年、ロシア海軍と共同して最初の無電局を建て、1899年座礁した軍艦アプラクシン号を救った。しかしマルコーニのようにはポポフの仕事は評価されず、1901年ペテルブルグ大学教授に戻り、1905年同大学電気技術学研究所長に選ばれた。
