Karl Johann Kiessling (February 6, 1839 – July 22, 1905) was a German physicist, mathematician, and botanist born in Culm; today Chełmno, Poland. == Biography == Karl Johann Hermann Kiessling was a well known ''physiklehrer'' (physics teacher) in the later half or the 19th century. Along with physics, he instructed students in the fields of chemistry, mathematics, and natural science (botany). The majority of his teaching career was held at the Gelehrtenschule des Johanneums, along with his elder brother Adolf Kiessling in Hamburg, Germany. Kiessling gained notoriety when he became intrigued by the twilight glow phenomena (Bishop's Ring) in the early morning and late evening skies over northern Europe during the winter of 1883/84. He had postulated, like others, that this was likely the result of the August 26th 1883, catastrophic eruption of the volcano Krakatoa located in Indonesia, east of Java. Kiessling proceeded to replicate the effect through laboratory experimentation. He designed and built a fog chamber in which he introduced precise amounts of dust and water vapour suspended in the gases within the chamber, and directed broad spectrum light through the mist. Kiessling's experimental results and documentation were successful and advanced the theories of meteorology as well as contributed to the development of the cloud chamber by Charles Thomas Rees Wilson used in particle physics to detect the paths of radioactive particles.〔("Johann Kiessling, the Krakatoa Event and the Development of Atmospheric Optics After 1883" ), ''The Royal Society. by WILFRIED SCHRÖDER AND KARL-HEINRICH WIEDERKEHR'', Hechelstrasse 8, D-28777 Bremen-Roennebeck, Germany.〕 Kiessling's work was recognized throughout the scientific community and mention of it was given in numerous scientific periodicals and journals in Europe and the United States.〔("Nature Magazine" ), ''edited by Sir Norman Lockyer'', Nature: Volume 32 1885 – Page 638, MacMillan and Co.
