A pioneering neurologist who mapped the brain's response to trauma, studying survivors of a deadly nightclub fire to understand psychological shock.
Alexandra Adler carved her own path in the shadow of her famous father, Alfred Adler, becoming a formidable neurologist and psychiatrist in her own right. Fleeing the rise of Nazism, she brought her Viennese training to the United States, where she joined the faculty at Harvard Medical School. Her most significant work emerged from tragedy: the 1942 Cocoanut Grove nightclub fire in Boston, which killed 492 people. Adler conducted a landmark study of the survivors, meticulously documenting the neurological and psychological sequelae of extreme shock and trauma. This work provided early, crucial insights into what would later be termed post-traumatic stress disorder. Throughout her career, she served as a vital interpreter and systematizer of Individual Psychology, ensuring her father's theories remained a living, clinical practice while advancing the understanding of the physical brain's role in mental life.

Alexandra was born in 1901, placing them squarely in The Greatest Generation. The events that shaped this generation — world wars, depression, and rapid industrialization — shaped the world they entered and the choices available to them.
