HUDSON, N.Y. – In ceramics circles, and particularly on the US antique show circuit, Wynn and Elizabeth Sayman were a constant and well respected presence, trading under the name Wynn A. Sayman Antiques. But when they weren’t buying and selling their specialty — 18th-century English ceramic wares — both worked as physicians. In fact, they met at the University of Chicago, where Wynn was a professor and Elizabeth, a student. In 1980 their shared passion for English ceramics served as the launch point for an antiques business based in Richmond, Massachusetts, where the Wynns resided.
