(45305) Paulscherrer was named on June 13, 2006 after the Swiss physicist Paul Scherrer (1890–1969) who, together with Peter Debye, developed the Debye-Scherrer method for determining the structure of crystals by means of X-rays in 1916 and, from 1930, increasingly turned to nuclear physics . The asteroid (30852) Debye was named after Peter Debye in 2002 .
