[1] In 1905 Harvey Brook was responsible for the restoration of Jacob's Well – a 15th century house associated with Holy Trinity Church, York[6][7] Following the construction of the Tempest Anderson Hall in the Yorkshire Museum he collaborated with E. Ridsdale Tate in founding and shaping the Museum of Medieval Architecture beneath it in 1912.
[4][8] He continued to be associated with the Yorkshire Philosophical Society until his death in 1943,[1] maintaining his post as Honorary Curator as well as becoming vice-president of the YPS in 1923[9] and part of the committee for the restoration of St. Mary's Abbey in 1939.
[10] Prior to the 1922 death of his colleague E. Ridsdale Tate, Harvey Brook's dedication to Medieval Architecture was described in one of his final lectures: "The arrangement in their new home (of the Medieval stonework from St. Mary's Abbey, York) was begun and carried on under the guidance of Mr. Harvey Brook, who, I may say, has with loving care tended these fragments from the moment they were touched by the workmen till they rested safely in a more spacious abode.
"[11] In 1913, Harvey Brook supervised the excavation and partial rebuilding of a portion of the North and East Cloister alleys.
[12] Brook was self-funded for much of the excavation of the Abbey[2] and devoted a great deal of time to the cataloguing and presentation of the architectural stonework.
