In 1973, church president Harold B. Lee asked Jacobsen if she would become the LDS Church curator. Jacobsen accepted and became a key figure in the construction of the Museum of Church History and Art. As a church curator, Jacobsen supervised the restoration of many church buildings, including the Promised Valley Playhouse in Salt Lake City; the E. B. Grandin building in Palmyra, New York; the Brigham Young home in St. George, Utah; the Jacob Hamblin home in Santa Clara, Utah; the Newell K. Whitney store in Kirtland, Ohio; and the interior of the Manti Utah Temple.
