Written by Shaun J. Hardy “Perhaps no building being erected at the present time has excited so much interest ... as has the new edifice in progress [at Broad Branch Road].  Certainly no structure has required so much precise care in workmanship and a thorough knowledge of building to meet the delicate needs of a building of this character.  It is the last word in scientific building.”
