When I was a kid my parents and I would go on lengthy trips of exploration on local buses, and one of the routes was the B-63 which ran down 5th and Atlantic Avenues to the waterfront. On the return trip I remember being amused by the factory building near Nevins that was emblazoned “Ex Lax” over its front entrance, since even as a kid I knew that was the name of the “chocolate laxative” which was then advertised heavily on TV.
It was indeed an Ex-Lax factory, but it closed sometime in the 1960s. It was an early residential conversion in 1979, when I was still attending St. Francis College a couple of blocks away. A few years ago I went on an Open House New York tour through one of the ultramodern residences that have been carved out of the old poop loosening factory, which once kept a “staff” of monkeys on hand for product testing. The monkeys’ old quarters, in which they were kept in cages, has been incorporated into one of the apartments.
