Born in White Plains, New York, and raised in Scarsdale, he pursued a degree in history from Harvard University, graduating in 1946.
This technological adoption led to the creation of The People’s Chronology, a work significant enough for Microsoft to acquire its rights for digital distribution.
[1] The People's Chronology stands out in Trager's bibliography for presenting a timeline of human events starting from 3 million B.C., based on fossil evidence.
The work includes diverse historical facts, from the introduction of Heroin by Bayer in 1898 to the commercial debut of cornflakes by the Kellogg.
Trager's works are used as reference materials in libraries and newsrooms, reflecting his dedication to documenting and analyzing historical events and trends.
