Alan Rosenberg started collecting at 15 and now has his own Manhattan gallery. The 39-year-old's collection focuses on midcentury American silver, modernist Finnish glass, ceramics from Europe and the States, as well as 20th-century furniture and Surrealist oils. "I deal in things I love, which form a very eclectic array," says Rosenberg, who will open a second space this spring in Hudson, New York, and make his Manhattan gallery appointment-only. "But they all speak to me in a special way." From $1,000 to $20,000; 212-989-4061; www.alanrosenbergwoa.com.
