The Boyce Thompson Institute was established by William Boyce Thompson with the goal of being able to improve world food supply through plant research. The Institute in Yonkers was constructed in 1924 but was moved from the Yonkers campus in the 1970s. The building was used for other operations until 1999. The property has been vacant ever since, although there is the possibility that it will be redeveloped.
