A Finnish teacher, writer, and translator, he moved easily between literature and scholarship. He is especially remembered for writing a book on Zacharias Topelius and for helping bring other works into Finnish.

by A. J. Sarlin
Aron Josef Sarlin (1866–1933), better known as A. J. Sarlin, was a Finnish lyceum teacher, writer, and translator. Available sources describe him as a school lecturer as well as a literary figure, and note that he also used the pen names A-i-s and Arkadius.
He was born in Tuusniemi on April 11, 1866, and died in Turku on September 29, 1933. His surviving bibliography in public-domain catalogs includes Zacharias Topelius: Elämä ja toiminta, which helped preserve the life and work of one of Finland’s major authors for later readers.
