Entitled: "Triplets William F., Robert J., and Henry L. Aldinger, all 18 years old, of Springfield, Long Island, New York, draw their uniforms and equipment after enlisting. Under army policy they will be kept in the same outfit." Identical triplets or quadruplets are very rare and result when the original fertilized egg splits and then one of the resultant cells splits again (for triplets) or, even more rarely, a further split occurs (for quadruplets). The odds of having identical triplets is unclear. Photographed by the US Army, 1943.
