Mark Evanier has the obit:
Glanzman got into comics in 1939, joining his brothers David and Louis who were also artists in the formative years of the industry. Like his brothers, he worked at first for Funnies, Inc., an agency that commissioned comic book stories and art and then sold that material to publishers. Sam’s early artwork and some writing he did seem to have appeared first in the pages of comics published by a short-lived firm called Centaur. His drawing can be seen in Amazing-Man Comics, Amazing Man having been created by Bill Everett who would soon be better known for The Sub-Mariner. Glanzman worked for other publishers (especially Harvey) but his career was interrupted by World War II
Glanzman best known works were memoirs of his time in the Navy and his work added to the body of narratives about this tumultuous time in human history.
