Carl Hering (Philadelphia, 19 March 1860 – 10 May 1926) was an American engineer involved in studies on electric batteries and electric furnaces. He also made discoveries on electromagnetic force.{{Cite web|title=Carl Hering|url=https://www.electrochem.org/hering/|access-date=2022-01-13|website=ElectroChemicalSociety|language=en-US}}{{Cite web |title=Carl Hering's Publications |url=https://ieeexplore.ieee.org/author/37322965100 |access-date=2022-05-09 |website=IEEE}}{{Clarify|date=January 2025}}

Biography

He was one of the sons of Constantine Hering, a pioneer of homeopathy in the United States.{{Cite web|title=Carl Hering, 1860 - 1926|url=https://www.myheritage.com/names/carl_hering|access-date=2022-01-13|website=www.myheritage.com}}{{Cite book|last=Hering|first=Carl|url=https://catalog.hathitrust.org/Record/002088534|title=Chronology of events concerning the life of Constantine Hering of Philadelphia, Pa., the father of homoeopathy in America.|date=1919|location=n.p.}} He studied mechanical engineering at the University of Pennsylvania in Philadelphia, where he earned his Bachelor's degree in 1880 and then stayed on to teach mathematics and mechanical engineering. In 1883, he began his studies in electrical engineering as Erasmus Kittler's first assistant at the Faculty of Electrical Engineering of TU Darmstadt, Germany, where the first chair of electrical engineering had been created the year before.

Upon his return to Philadelphia in 1886, he founded a consulting firm that he continued until his death, specializing in work on electric furnaces{{Cite journal |last=Hering |first=Carl |date=1912 |title=Discussion on "Thirty Years' Progress in the Electric Furnace" (FitzGerald), Boston, Mass., June 25, 1912 |url=https://ieeexplore.ieee.org/document/4768472 |journal=Transactions of the American Institute of Electrical Engineers |volume=XXXI |issue=1 |pages=1188–1190 |doi=10.1109/T-AIEE.1912.4768472 |s2cid=51649546 |issn=2330-9431}} and electrolysis, electrochemical and electrophysical processes.{{Cite book |last=Rechcigl Jr. |first=Miloslav |title=American Men and Women in Medicine, Applied Sciences and Engineering With Roots in Czechoslovakia: Practitioners - Educators - Specialists - Researchers |publisher=AuthorHouse |date=February 17, 2021 |isbn=978-1665514989 |location=Bloomington (IN)}} In 1887, he obtained his Master of Science also at the University of Philadelphia. In 1889, he participated in the World Exposition in Paris{{Cite book |last=Hering |first=Carl |title=Electricity at the Paris Exposition of 1889 |publisher=Andesite Press |year=2015 |isbn=9781296695194 |location=London |orig-date=1889}} on behalf of the American government and around 1890, he studied the possibility of making electric batteries, obtaining several patents on the subject.

In 1902, together with E. F. Roeber, C. J. Reed, and J. W. Richards, he founded the American Electrochemical Society, of which he was president from 1906 to 1907. He was appointed officer of Public Education by the French government in 1889 and decorated a Knight of the Legion of Honor in 1891.

In 1908, Carl Hering developed an experiment on electromagnetic induction to study its fundamental laws, an experiment similar to later Blondel's experiments.{{Cite journal |author=Carl Hering |year=1908 |title=An Imperfection in the Usual Statement of the Fundamental Law of Electromagnetic Induction |url=https://ieeexplore.ieee.org/document/4768122 |journal= Transactions of the American Institute of Electrical Engineers|volume=60 |issue=946|pages=1341–1351 |doi=10.1109/T-AIEE.1908.4768122 |s2cid=51645558 |url-access=subscription }}
