Perched on a hill at Ann Street and Observatory Street, the Detroit Observatory has overlooked the Huron River valley in Ann Arbor since 1854. It occupies the corner of Ann Street and its namesake Observatory Street, perched on a hill overlooking the Huron River valley. Built in 1854, this was the university's first scientific research facility and one of the oldest observatories of its type in the nation. In recognition of its importance it was designated a Michigan State Historic Site in 1958 and placed on the National Register of Historic Places in 1973.
The story begins with Henry Philip Tappan, inaugurated as president of the University of Michigan in December 1852, who appealed to the citizens of Michigan for research and laboratory space. He was soon approached by Detroit businessman and former Michigan Attorney General Henry N. Walker, who offered help. Tappan suggested an observatory; Walker agreed to spearhead a fundraising drive and soon raised over $7,000 from the citizens of Detroit. That total increased to $18,760 over the next few years, making this building possible.
