Johann Wilhelm Ritter was born ion 16 December 1776 in Samitz (then
Silesia, Germany, now Chojnow, Poland). After working for five
years as an apprentice
to a pharmacist, in 1795 a small inheritance allowed
to enter the University of Jena ta the age of nineteen. There,
he benefited from the scientific mentorship of Alexander von Humboldt
(1769-1859), who reinforced his interests into electrical experiments.
In 1801 He was
appointed to the court of Ernst II, duke of Gotha-Altenburg,
and in 1804 moved to the Bavarian Academy of Science in Munich,
where he remained until his untimely death on 23 January 1810.
Ritter was interested primarily in electricity, in particular
electrochemistry and electrophysiology, areas in which he made
many remarkable discoveries. In 1799 he carried out electrolysis of water,
and in 1800 investigated the process of electroplating. In 1801 he
observed thermoelectrical currents, and investigated the artificial
electrical excitation of muscles.
In 1802-1803 he built the first dry cell battery and accumulator.
In 1801 Ritter discovered ultraviolet radiation by chemical means.
This foray into spectroscopy
was motivated by the discovery of infrared radiation by
William Herschel in 1800, coupled
to his general belief in electrical polarity pervading Nature:
invisible radiation beyond the visible red simply had to be paired
to invisible radiation beyond the violet, a speculation in line
with the Naturphilosophie he espoused when engaging
in philosophical theorizing.
Ritter had a difficult writing style, a marked
tendency to speculate to excess,
and procrastinated heavily when it came
to publishing detailed accounts of his
investigations and discoveries. For thses reasons, many of his findings
went unnoticed, only to be soon independently rediscovered by
other scientists. In the last years of his life,
his scientific credibility was also damaged
by his interest in occult phenomena, and more importantly by the inability
of other scientists to reproduce his experiments in this area.
Thus dismissed by most of his scientific peers, facing severe
financial difficulties
and family illnesses, Ritter died a embittered man a few weeks after
his thirty-third birthday. It took over a century before his
scientific work was given due credit.
