Lewis Yablonsky, one of the first generation of pioneering psychodramatists, has died at the age of 89. He was was an authority on youth gangs, hippies and drug addicts whose rough-and-tumble early years gave him insights others lacked.
He specialized in sociology and surely his psychodrama mixed well with that field; he wrote quite a bit about gangs and criminology. His 1992 book Psychodrama: Resolving Emotional Problems Through Role-Playing was translated into German, Italian and Spanish.
