A tribute to Hugo P. Kortschak: The man, the scientist and the discoverer of C4 photosynthesis.

Hugo P. Kortschak, a shy, quiet Quaker with unbelievable generosity toward mankind; an accomplished musician; and a dedicated, tenacious, and brilliant scientist, who spent his entire professional career working for a single employer in a commercially-oriented research organization, made one of the outstanding contributions to biological science of the past century. With his colleagues in the Hawaiian sugar industry, he discovered the C4 pathway of photosynthesis.
