Philipp Ludwig von Seidel

Philipp Ludwig von Seidel ([fɔn ˈzaɪdəl]; 24 October 1821 in Zweibrücken, Germany – 13 August 1896 in Munich, German Empire) was a German mathematician.

He was the son of Julie Reinhold and Justus Christian Felix Seidel.

[1] Philosopher & math theorist Imre Lakatos credits von Seidel with discovering, in 1847, the crucial analytic concept of uniform convergence, while analyzing an incorrect proof put forth earlier by Augustin-Louis Cauchy.

His doctoral students include Eduard Study and Hermann Wiener.
