October is notable for the birth of several important figures in the world of science. Karl Weierstrass, a renowned German mathematician who fundamentally contributed to the theory of functions, was born on this day in 1815. Furthermore, the birth of J.F.W. Adolf Ritter von Baeyer, a German chemist who won the Nobel Prize in Chemistry in 1905 for his work on organic dyes and hydroaromatic compounds, also falls on October 31, 1835. The same date in 1847 marks the birth of Galileo Ferraris, an Italian physicist celebrated for his pivotal role in developing alternating current (AC) power systems and the induction motor.
