Emil Chistoforovich Lenz, whose fundamental contribution to electrodynamics and Russian geography, was born on February 24, 1804 in the town of Dorpat (which is now Estonian Tartu, and long ago the town belonged to ancient Rus’ and was called Yuriev).
In 1820 Emil Lenz graduated from the gymnasium and entered the University of Dorpat. Lenz’s independent scientific activity started in 1823, when he joined a round-the-world expedition on the “Predpriyatie” sloop as a physicist, recommended by university professors. Fast thought of young scientists resulted in development of unique equipment for deep oceanographic observations – a depth indicator hoist and water sampler. During the trip Lenz performed oceanographic, meteorological and geophysical observations in Atlantic, Indian and Pacific oceans. In 1827 the scientist summarized his data and reported them to the Academy of Sciences in 1828. This enormous work brought him a title of associate professor of Academy of Sciences. In 1829 and 1830 Emil Lenz perform geophysical research in Russian south – the scientists took part in the first ever climb of Mount Elbrus and measured its height by means of barometric method. Later Lenz used the same technique for discovering that Caspian sea level was lower than Black sea level. Same year the researcher performed gravitational and magnetic measurements and, after returning to Saint Petersburg, reported the results in 1832 and 1836.
