Archibald Scott Couper (; 31 March 1831 – 11 March 1892) was a Scottish chemist who proposed an early theory of chemical structure and bonding.

Josephine Caroline Lang (14 March 1815 – 2 December 1880) was a German composer. Josephine Lang was the daughter of Theobald Lang, a violinist, and Regina Hitzelberger, opera singer. Her mother taught young Josephine how to play piano, and from age five it became apparent that Josephine was possessed with great potential as a composer. As early as age eleven Josephine started giving piano lessons herself. Through her godfather, Joseph Stieler, Josephine was exposed to some of the greatest artists of her time. Both Felix Mendelssohn and Ferdinand Hiller went to great lengths to ensure that Lang learned the proper theory for song-writing, and used their connections to publish Lang's music. Even Robert Schumann published a song of Josephine's in Neue Zeitschrift für Musik in 1838.
Walter Gramatté (8 January 1897 in Berlin – 9 February 1929 in Hamburg) was a German expressionist painter who specialized in magic realism. He worked in Berlin, Hamburg, Hiddensee and Barcelona.

Erich Bessel-Hagen (12 September 1898 in Charlottenburg – 29 March 1946 in Bonn) was a German mathematician and a historian of mathematics.Erich Paul Werner Bessel-Hagen was born in 1898 in Charlottenburg, a suburb, later a district in Berlin. He studied at the University of Berlin where in 1920 he obtained a Ph.D. in mathematics under the direction of Constantin Carathéodory.
His reputation was that of a gentleman as well as a conscientious intellect. This was averred in the early 1940s, when the ruling Nazis increased their persecutions of German officials who have Jewish ancestry. After Felix Hausdorff (a professor 30 years his senior) had been retired and placed under restrictions, Bessel-Hagen became the only former colleague who visited him regularly. On noticing that Hausdorff used private math researches to while away time, he started bringing him books he had borrowed from a library which no longer welcomed Jews.
