A German surname meaning 'eagle,' also referring to Alfred Adler, the influential Austrian psychologist who developed individual psychology.
German 'Adler' from Middle High German 'adelar', from Old High German 'adalar' meaning eagle. The surname derives from the bird name, likely originally a nickname or heraldic reference.
Alfred Adler coined the term 'inferiority complex' and was among the first to emphasize social factors in psychology, breaking from Freud's focus on sexuality. The eagle symbolism in his surname is fitting, as eagles represent vision and perspective - qualities essential to his psychological insights.
