At the same time, he was a philatelist.

，他个集邮家。

Since the 1950s, the post office has had philatelists–stamp collectors–sit on a committee that weighs in on stamp design.

自 20 世纪 50 年代以来，邮局一直邀请集邮家（集邮者）入负责邮票设计委员会。

As hard as it might be to imagine, a federally sponsored mail-in poll about postage stamps took off in a huge way–and not just among philatelists.

尽管很难想象，一项由联邦政府赞助于邮票邮寄民意调查取得了巨大成功，而且不仅仅在集邮爱好者中。
