Adolf Ferdinand Weinhold (born May 19, 1841 in Zwenkau , † July 2, 1917 in Chemnitz ) was a German physicist and chemist .

Weinhold was the fourth child of the royal court advisor Friedrich Moritz Weinhold and spent his childhood in Zwenkau near Leipzig . From 1857 to 1861 he studied chemistry at the Universities of Leipzig and Göttingen, primarily chemistry with Otto Linné Erdmann and Friedrich Wöhler , before finding employment as an assistant at the agricultural research station in Chemnitz. In 1864 he became a trial physics teacher at the royal trade school in Chemnitz from 1865 . In 1870 he received the title of professor and in 1873 due to his work on "Measuring High Temperatures" from the University of Leipzig the academic degree of Dr. phil.

Weinhold was one of the initiators of the first city power plants based on three-phase current in Chemnitz, Dresden, Leipzig and Plauen.

In his textbook "Physical Demonstrations" in 1881 he described a vacuum jacketed bottle for laboratory purposes. However, as early as 1874 , James Dewar was using a double-walled evacuated vessel made of mirrored glass to store liquefied gases, which is still called a Dewar vessel in his honor . Reinhold Burger from Pankow took up the idea of ​​the vacuum jacket and, on October 1st, 1903, patented a vacuum jug for everyday use that was mechanically more robust.

The following buildings bear his name in his honor:

  • the Zwenkau market development "Weinhold-Arkade"
  • the "Adolf-Ferdinand-Weinhold-Bau" of the TU Chemnitz
