== Life ==
Johann Michael Ekling was the posthumous son of the army surgeon Joseph Ekling. His mother was Anna Maria Eurosina Ekling, née Stitzbarth. He was born in the suburb of Matzleinsdorf in Vienna. At the age of 33 he married Theresia Schwarz with whom he had five sons and a daughter. In the years to follow he cooperated closely with mathematics and physics professors Andreas von Baumgartner (German Wikipedia)〔(Electromagnetic apparatus built for Baumgartner in 1830 (University of Innsbruck) )〕 and Andreas von Ettingshausen of the University of Vienna. He produced artificial magnets on behalf of Baumgartner〔''Wiener Zeitung'' of 26 January 1833, p. 95〕 and one of the first photographic apparatuses in Austria (1839)〔Emil-Heinz Schmitz, ''Handbuch zur Geschichte der Optik: Das XIX. Jahrhundert'', Bonn 1983, p. 9〕 following instructions by Ettingshausen,〔''Bohemia: oder Unterhaltungsblätter für gebildete Stände'', 1840; no page number〕 who had worked with Daguerre. By 1844 he is referred to as a "university mechanic".〔''Verhandlungen der k.k. Gesellschaft der Ärzte zu Wien'', Vienna 1844, p. 25〕 An announcement in a paper describes his range of products as follows: "() makes all sorts mathematical and physical instruments and apparatuses, air pumps with glass barrel chambers, travel barometers, goniometers,〔Ekling built this instrument according to instructions received from Friedrich Mohs (1773-1839)〕 chemical and mineralogical apparatuses".〔''Notizen über Produktion, Kunst, Fabriken und Gewerbe'', Wien 1833, p. 48〕 His multiplicator was used for the analysis of mineral waters among other things and praised for its sensitivity.〔Adolph Pleischl, ''Ueber die Thermalwasser zu Gastein und Carlsbad in chemisch-physicalischer Hinsicht'', 1846, p. 6〕 Ekling was granted patents for induction machines, cameras and improvements to the Bain telegraph, which were taken over by the Austrian railway. Ekling’s last invention was a "Galvanic Induction Machine for Medical Purposes".〔Insert to ''Faust. Poligrafisch-illustrirte Zeitschrift für Kunst, Wissenschaft, Industrie und Unterhaltung'', 1854; no page〕
His reputation as a mechanic is documented in the Austrian Law Gazette for 1850: "The most recommendable mechanic in Vienna, and as regards more sophisticated optical equipment, the only one to be recommended, is Eckling."〔''Gesetzblatt für das Land Österreich'', 1850, p. 542〕 Among these instruments we find the heliostat in the picture alongside.〔A. Adolf Schmid, Wien und seine nächsten Umgebungen mit besonderer Berücksichtigung wissenschaftlicher Anstalten und Sammlungen, Vienna 1852, p. 92.〕 Young mechanics from Germany like Rudolph Carl Adolph Dolberg (1817-1863) and Adolph Hermann Friedrich Petri (1819-1895)〔(Jürgen Hamel, Über die mechanisch-optischen Werkstätten "Dolberg" und "Dolberg & Petri" in Rostock )〕 were apprenticed to Ekling. Johann Leopolder, who later ran his own large Telegraph and Telephone Company was also one of his apprentices and later his foreman, until he started his own establishment in 1850.〔''Die Gross-Industrie Österreichs'', vol. 3, 1898, p. 250.〕
In 1860 Ekling sold his premises at 25 Erdbergstrasse to his neighbour Rudolf Ditmar who owned a rapidly expanding kerosine lamp factory.〔''Wiener Geschichtsblätter'', vol. 56, issues 1-4, Verein für Geschichte der Stadt Wien, 2001, p. 3〕 He died a gentleman of independent means at Landstrasse/Vienna in 1876.
