 Johann Christian Poggendorff
Poggendorff immediately put himself in communication with the publisher, Barth of Leipzig, with the result that he was installed as editor of a scientific journal, Annalen der Physik und Chemie, which was to be a continuation of Gilberts Annalen on a somewhat extended plan.
In the course of his fifty-two years editorship of the Annalen Poggendorff could not fail to acquire an unusual acquaintance with the labors of modern men of science.
This knowledge, joined to what he had gathered by historical reading of equally unusual extent, he carefully digested and gave to the world in his Biographische-literarisches Handwörterbuch zur Geschichte der exacten Wissenschaften, containing notices of the lives and labors of mathematicians, astronomers, physicists, and chemists, of all peoples and all ages.

Poggendorff studied problems in electricity and magnetism, he developed a mirror galvanometer and, actually, he gave the name "galvanometer" to a physical instrument measuring an electric current.
Poggendorff built a system in which he installed a small flat mirror to reflect a relatively narrow beam of light.
The design of a mirror galvanometer comprises a coil of wire wound on a soft iron core suspended in the magnetic field of a permanent magnet - this coil is suspended generally by means of a strip of phosphor bronze wire and located centrally between the poles of the permanent magnet.

 Julius Robert von Mayer - Wikipedia, the free encyclopedia
He sent a paper to Johann Christian Poggendorff's Annalen der Physik in which he postulated a Erhaltungssatz der Kraft, by which he meant a conservation law energy.
However, owing to Mayer's lack of advanced training in physics, it contained some fundamental mistakes and was not published.
Mayer continued to pursue the idea steadfastly and argued with the Tübingen physics professor Johann Gottlieb Nörremberg, who rejected his hypothesis.

 History of Scholarly Societies: Poggendorff's Biographisch-Literarisches Handwörterbuch
Both society journals and independent journals were documented, and supplied with the full name, publication years and volumes all drawn from library catalogues.
This work was tiresome in the extreme, in no small part because of the cryptic manner in which Poggendorff abbreviated many of the titles.

With these words, written in 1863 at the start of the "Pro- and epilogue by the author", Johann Christian Poggendorff presented the first volume of his work to the reader, a work that was to become "the Poggendorff".
The author, a physicist and extraordinary professor at the University of Berlin, is still known today in the field of mechanics as the inventor of the Poggendorff Scale.
His "Biographisch-literarisches Handwörterbuch der exakten Naturwissenschaften" (Concise Biographic-Literary Dictionary of the Exact Sciences) is a reference steeped in tradition, that has been publishing "accounts of the lives and achievements of mathematicians, astronomers, physicists, chemists, mineralogists, geologists, biologists" and scientists from other disciplines since 1863.

This highly oxidizing and toxic mixture needed constant replacement as it became contaminated with zinc.
Introduction: This potassium bichromate cell was developed by Johann-Christian Poggendorff from Bunsen's carbon/zinc cell with a nitric acid electrolyte.
It was very popular in laboratories and telegraph relay stations because it did not give off the nitric acid fumes that Bunsen's cell did and it gave a useful output of about 1.8 volts.
