Emil Lenz (English: /lɛnts/; German: [lɛnts];
also Emil Khristianovich Lenz, Russian: Эмилий
Христианович Ленц; 12 February 1804 – 10 February
1865), usually cited as Emil Lenz, was a Russian physicist of
Baltic German ethnicity. He is most noted for formulating Lenz's law
in electrodynamics in 1834.

Lenz was born in Dorpat (nowadays Tartu, Estonia), at that time in the
Governorate of Livonia
Governorate of Livonia in the Russian Empire. After completing his
secondary education in 1820, Lenz studied chemistry and physics at the
University of Dorpat. He traveled with the navigator Otto von
Kotzebue on his third expedition around the world from 1823 to 1826.
On the voyage Lenz studied climatic conditions and the physical
properties of seawater. The results have been published in "Memoirs of
the St. Petersburg Academy of Sciences" (1831).
After the voyage, Lenz began working at the University of St.
Petersburg, Russia, where he later served as the Dean of Mathematics
and Physics from 1840 to 1863 and was Rector from 1863 until his death
in 1865. Lenz also taught at the
Petrischule in 1830 and 1831, and at
the Mikhailovskaya Artillery Academy.
Lenz had begun studying electromagnetism in 1831. Besides the law
named in his honor, Lenz also independently discovered Joule's law in
1842; to honor his efforts on the problem, it is also given the name
the "Joule–Lenz law," named also for James Prescott Joule.
Lenz eagerly participated in development of the electroplating
technology, invented by his friend and colleague Moritz von Jacobi. In
1839, Lenz produced several medallions using electrotyping. Along with
the electrotyped relief produced by Jacobi the same year, these were
the first instances of galvanoplastic sculpture.
Lenz died in Rome, after suffering from a stroke.
A small lunar crater on the far side of the moon is named after him.
