Who founded dependent personality disorder?

Dependent Personality Disorder (DPD) is not attributed to a single founder, but rather it emerged as a recognized psychological condition through the work of various psychologists and psychiatrists. The disorder was included in the first edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-I) published in 1952, reflecting the contributions of multiple researchers in personality and clinical psychology. The understanding and definition of DPD have evolved over time as more research has been conducted in the field of personality disorders.
