Yes, the Brooklyn Union Gas building was at 180 Remsen St., and was sold to St Francis College some time around 1960-61. I spent most of my last year at St. Francis in 62-63, and the building had been completely renovated by then. But the old site, at 35 Butler St. was still used for all of the science classes & labs . . . I don't know when they moved them (I graduated in '63). Before they moved to Remsen, the college rented space in a building on Court Street (somewhere around 24 Court St.), where the School of Business was. It also had the largest classroom in the college, which was used for the really popular courses. It was a real trick to get from the Butler St. campus to the Court St. building in the 10 minutes between classes . . . you had to RUN. God help you if the instructor you had at Butler held the class over for even 2 minutes . . . or if the traffic on Atlantic Ave. was heavy.
