It took a year for actor Judd Hirsch to find an apartment, but the hunt is finally over. The Taxi veteran and current star of CBS’s math-and-forensics show Numb3rs, who sold his four-bedroom, six-bath co-op on Park Avenue last year for more than $4 million, spends much of his time at a retreat in the Berkshires (when he’s not on set somewhere), but had always kept a Manhattan base, too. Now he has one again, though it’s definitely scaled-down compared with his former abode: According to city records, Hirsch just closed on a two-bedroom, two-bath condo in the East Nineties that he bought last month for $950,000. The 1,200-square-foot apartment has views of the river and the George Washington Bridge, and sits on a high floor of a building loaded with amenities, including a swimming pool, a playground, and a garage. A representative says Hirsch declined to comment on the sale.
