In 1888, the musicologist Hugo Riemann recommended Busoni to Martin Wegelius, director of the Institute of Music at Helsingfors (now Helsinki, Finland, then part of the Russian Empire), for the vacant position of advanced piano instructor. This was Busoni's first permanent post. Amongst his close colleagues and associates there were the conductor and composer Armas Järnefelt, the writer Adolf Paul, and the composer Jean Sibelius, with whom he struck up a continuing friendship. Paul described Busoni at this time as "a small, slender Italian with chestnut beard, grey eyes, young and gay, with ... a small round cap perched proudly on his thick artist's curls".
