philatelist fə-ˈla-tə-list noun
: a collector and student of postage stamps
The word philatelist has appeared in four articles on NYTimes.com in the past year, including on Jan. 10 in the obituary “Harold Burson, a Giant in Public Relations, Dies at 98” by Robert D. McFadden:
Mr. Burson collected stamps and looked like an old-world philatelist: contemplative, analytical. He was a small man with a gentle face, appraising eyes behind improbably oversize glasses and a bald pate with a fringe of gray touching the ears. The voice was soft, patient. To a question, he would think a bit, and then have something to say.
