11519 Adler           Discovered 1991 Apr. 8 by E. W. Elst at the European Southern Observatory.
Alfred Adler (1870-1937) was an Austrian psychiatrist who introduced the term "inferiority feeling" (inferiority complex) into psychology: mental health is characterized by reason and social interest, mental disorder by inferiority, self concern and superiority over others". In 1934 the Austrian government closed his 30 clinics.
