Otto Schlicht was a German-American manufacturer of concertinas in Chicago.
Schlicht arrived in the United States from Germany around 1900, having worked on German-type concertinas there. He applied his knowledge to the production of concertinas, and began[when?] producing models under the brand-names Patek, Pearl Queen, and Peerless for music shop in Illinois.[1][2]
He transitioned to owning his own concertina workshop, where he produced his brands until 1950. Shortly after he ceased working, in 1952 concertina maker Christy Hengel purchased Schlicht's concertina-making equipment, which had been stored in a basement since the workshop closed, for $1500, moving it to his own shop in New Ulm, Minnesota, producing chemnitzer concertinas under the Helgel name.[3]
