Knight Mangum Building KMB year occupied: 1943 Year vacated: 2008 Originally not part of BYU, the KMB was built by the National Youth Administration as an auto shop. It was purchased by the university in 1943 and was used as a women's dormitory. The building at that point consisted of the lower portion. From 1946-1952 an upper addition was built. Originally the upper portion was designated the Knight Mangum Building while the lower portion was designated the Social Hall. The Social Hall was used by the music department until the Harris Fine Arts Center was completed. After this the Language Training Mission (predecessor to the Missionary Training Center) moved in. After the LTM moved to the current cite of the MTC, the Knight Mangum Building was used by the history department, the sociology department, the school of social work, all parts of the College of Family, Home and Social Sciences, the Joseph Fielding Smith Institute for LDS Church History, the BYU Young Ambassadors and also housed a computer lab. The building was specifically named after Lucy Jane (Jennie) Brimhall Knight (George H. Brimhall's daughter and Jesse Knight’s daughter-in-law) and Jennie Knight Mangum (Jesse Knight’s daughter), two sisters-in-law who were lifelong friends of the university.
