Born in 1905 in the center of the crumbling Austro-Hungarian Empire, Viktor Frankl was a witness to the great political, philosophical, and scientific upheavals of the twentieth century. In these stirring recollections, Frankl describes how as a young doctor of neurology in prewar Vienna his disagreements with Freud and Adler led to the development of the third Viennese School of Psychotherapy, known as logotherapy; recounts his harrowing trials in four concentration camps during the War; and reflects on the celebrity brought by the publication of Man's Search for Meaning in 1945.
