Alfred Adler, pioneering psychologist and founder of the school of individual psychology, whose lifelong pursuit of research and teaching shaped the field of psychotherapy, passed away on May 28th 1937, at 67 years old. Adler was born in Vienna, Austria in 1870 and earned a medical degree from the University of Vienna at the age of 23. He began to focus on a holistic approach to understanding the human psyche, making him the first psychologist to emphasize understanding of an individual’s personality within a social context. With these ideas, Adler founded the school of individual psychology in 1912; in it, he proposed the pioneering theory of inferiority complex, asserting that a person's view of the world is determined by how they view themselves. Adler's work had a profound influence on psychology and psychotherapy, and his theories were adopted and extended by many of his contemporaries, including Karen Horney and Viktor Frankl. He was quite popular in the European psychotherapy community, and his ideas were disseminated worldwide through numerous books, lectures, and the training of students. Alfred Adler was an innovative thinker who laid the foundation for modern psychotherapy. His methods and theories continue to shape the field to this day.
