NEJM History


John Collins Warren, a Boston physician and scholar, collaborated in 1811 with colleague James Jackson to establish the first medical journal in New England, publishing the first quarterly edition of the New England Journal of Medicine and Surgery and the Collateral Branches of Medical Science (Boston) in January of 1812.


In 1921, the journal merged with the Boston Medical Intelligencer to become the Boston Medical and Surgical Journal; it also began weekly publication that year and was purchased by the Massachusetts Medical Society.


Renamed to the New England Journal of Medicine in 1928, the journal is known for many firsts in medicine, including the first to publish a full description of spinal disk rupture (1934) and the first to document success in treating early childhood leukemia (1948).


NEJM becomes the first American medical journal to receive the distinguished Polk Award for journalistic excellence.


Digitization of NEJM content begins with the launch of NEJM.org.


NEJM launches the NEJM Archive (1812-1989), providing searchable access to an additional 150,000+ NEJM articles dating back to 1812.
