LIFE photographers followed a variety of paths to reach the heights they attained, but certain trends are consistent. Henry Groskinsky (1934-2018) is a worthy exemplar of the noble tradition of beginning as a LIFE assistant. Larry Burrows began by drying prints, Cornell Capa and Mark Kauffman started out in the lab, and Carlo Bavagnoliworked as an assistant to Dmitri Kessel in Italy. Said Groskinsky of LIFE, “There’s no school like it in the world.” For nearly a decade, at championship fights and political conventions, he was there ahead of time, setting giant strobe lights to illuminate the vast arenas. On the road he learned by developing test film in motel bathrooms. These apprentice labors imbued Groskinsky with a formidable array of technical skills, so that in the end he became a master of both the intimate and the grand.
