Harold W. McGraw, Jr., chairman emeritus and former CEO of the McGraw-Hill Companies, has passed away at 92-years-old.

McGraw began his career at his grandfather’s company as a sales rep. During his tenure at the helm of the company, McGraw-Hill published authors that included Vladimir Nabokov and Marshall McLuhan. At Princeton University (his his alma mater) McGraw endowed the The Harold W. McGraw, Jr. Center for Teaching and Learning , funded the editing of Albert Einstein‘s papers, and established the McGraw Distinguished Visiting Professors writing course.

Here’s more from the company: “As CEO of McGraw-Hill, he was always closely connected with employees, sending them hand-written notes, walking the corridors, and eating lunch in the company cafeteria. He advised employees to ‘make sure you get in a job you really enjoy, for doing worthwhile work for a worthwhile mission ought to be exciting and fun.’”
