Ludwig Aaron Gans

Ludwig Aaron Gans (born 17 July 1794 in Celle, died 27 June 1871 in Frankfurt) (also spelled Ludwig Ahron Gans) was a German industrialist and owner of the company Cassella.

In 1814 he moved in with the related Goldschmidt family in the Frankfurt Jewish Alley and joined the firm Cassel & Reiss, owned by Leopold Cassella, as an apprentice.

In 1828, Gans married Rosette Goldschmidt (1805–1868), a niece and de facto adopted daughter of Leopold Cassella, and became a partner in the firm in the same year.

The oldest son Friedrich Ludwig Gans joined Cassella & Co. as an apprentice in 1847 and would become a major industrialist and philanthropist in Germany; he converted to Christianity in 1885 and was ennobled in 1912.

The younger son Leo Gans was also a noted industrialist, philanthropist and chemist.
