Simon E. Jacobsohn (December 24, 1839 in Mitau, Kurland, Russian Empire – October 3, 1902 in Chicago, Illinois, United States[1]) was a Latvian-American violinist.

In 1872 he immigrated to the United States to become concertmeister and solo violinist in the orchestra which Theodore Thomas was at that time conducting in New York City.

Before going to the US, Jacobsohn had been concertmeister at Bremen, at which time he organized a string quartet which became very famous throughout Europe.

Among his noted pupils while in Cincinnati were Max Bendix, Nahan Franko, Nicholas Longworth, Henry Burck, Michael Banner, Miss Currie-Duke, Theodore Binder, Carl Heinzen, Ollie Torbett, Madge Wickham, and Hugh McGibeny.

Jacobsohn also toured the United States with pianist William H. Sherwood, his good friend.
