Definition
Mortimer L. Neinken (1900 – 1975) was an American philatelist renowned for his scholarly research on early United States postage stamps, particularly the issues of 1847–1851. He authored several authoritative reference works that remain standard references among collectors and researchers.
Overview
Born on March 6, 1900, Neinken pursued a career in business while maintaining a lifelong dedication to philately. He became a leading specialist in the study of the first United States stamp series, producing detailed plating analyses, rarity assessments, and historical context for these issues. His publications, most notably The United States 1847‑1851 Issues (published in two volumes, 1950–1952) and United States Postage Stamps: The First 20 Years (1964), combined meticulous examination of stamp varieties with comprehensive documentation of known examples.
Neinken was an active member of several philatelic societies, including the Collectors Club of New York and the American Philatelic Society (APS). He contributed articles to The American Philatelist and other journals, and he served on expert committees that authenticated rare stamps. In recognition of his contributions, he was posthumously inducted into the APS Hall of Fame in 1976.
Etymology/Origin
The surname “Neinken” is of Germanic origin, derived from a variant of the personal name “Nienk” or “Nienke,” historically used in northern Germany and the Netherlands. The given name “Mortimer” originates from the Old French Mortemer, meaning “dead pond,” and was adopted into English as a personal name during the medieval period.
Characteristics
- Specialization: Focus on United States postage stamps issued between 1847 and 1851, including the 3‑cent 1851 “Dime” series and the 5‑cent “Half‑dollar” issues.
- Methodology: Employed plating techniques—comparing minute differences in printed stamps to determine their position on the original printing plates. His work established reference plates that are still used by collectors to identify plate positions and varieties.
- Publications: Authored two‑volume The United States 1847‑1851 Issues (1950‑1952) and United States Postage Stamps: The First 20 Years (1964). Both works are cited for their exhaustive listings of known specimens, provenance data, and expert commentary on authenticity.
- Recognition: APS Hall of Fame inductee (1976); frequent speaker at philatelic conventions; consulted by major auction houses for expert opinions on early U.S. stamps.
- Legacy: Neinken’s research set a methodological benchmark for later philatelic scholarship. His reference plates continue to be reproduced in modern catalogues, and his analytical approach influences contemporary studies of early postage‑stamp production.
