I want to know the answer to the following question:
Which school was used as the engineering and sciences school until 1956?
All the background I'm provided with is that "Several are associated with members of the Vanderbilt family, including Vanderbilt Hall, Phelps Hall, St. Anthony Hall (a commission for member Frederick William Vanderbilt), the Mason, Sloane and Osborn laboratories, dormitories for the Sheffield Scientific School (the engineering and sciences school at Yale until 1956) and elements of Silliman College, the largest residential college.". Is that enough to answer the question?
Answer: yes
