Naming

The prize was originally named to honour the Finnish mathematician

who had died a year before the prize's creation in 1981. The medal featured a profile of Nevanlinna, the text "Rolf Nevanlinna Prize", and very small characters "RH 83" on its obverse. RH refers to

Raimo Heino Raimo Heino (September 13, 1932 – November 30, 1995) was a Finnish designer of coins, relief figures and medallions. He was the designer of the Finnish 2 euro coin. All designs feature the 12 stars of the EU and the year of imprint on the front ...

Finnish Volunteer Battalion of the Waffen-SS From 1941 to 1943, 1,408 Finns volunteered for service on the Eastern Front of World War II in the ''Waffen-SS'', in units of the SS Division Wiking. Most of these volunteers served as motorized infantry in the Finnish Volunteer Battalion ...

during World War II. Soifer discussed Nevanlinna's wartime activities in a 2015 book, and forwarded his personal and his organization’s requests to the Executive Committee of IMU to change the Prize's name. In July 2018, the 18th General Assembly of the IMU decided to remove the name of Rolf Nevanlinna from the prize. It was later announced that the prize would be named the IMU Abacus Medal.
