Friedrich Heinrich Albert Wangerin (18 November 1844 – 25 October 1933) was a German mathematician.

Wangerin was born on 18 November 1844 in Greifenberg[2] Pomerania, Prussia (now Gryfice, Poland).

He studied at the gymnasium at Greifenberg and completed his final examination with an "excellent" grade in 1862.

In spring 1862, Wangerin entered the University of Halle-Wittenberg, where he studied Mathematics and Physics.

The chair of ordinary professor had fallen vacant because of the death of Eduard Heine, the former teacher of Wangerin.

[3] Wangerin was known for his research on potential theory, spherical functions and differential geometry.

In 1909, he wrote an article on optics (Optik ältere Theorie) for the physics volume of the same encyclopaedia.
