Stefan T. Vail Cooperative House

[1] The building proper was constructed in 1848 by the family of Thomas and Margaret Mitchell, completed in the American Greek Revival style which typifies many Ann Arbor-area homes of the period.

[2] It has been recognized by the Ann Arbor Historical Commission; one of the pillars on the front porch bears a plaque which identifies it as the Hubbell Gregory House.

[1] Afterwards it became the residence of the family of Horace Greely Prettyman, who owned the Ann Arbor Press and White Swan Laundry.

[4] While camping near Mount Olympus in Greece, Stefan Vail was shot and killed by an army deserter who mistook him for a pursuing officer.

[5] His death was called a "tragedy" by his senior colleague at the Harvard Economics Department, Seymour Harris, who wrote that Valavanis was "brilliant, imaginative, and a first–class scholar and teacher"; according to Seymour, Valavanis's econometrics textbook had "pedagogical strength", proceeding "more by statements of problems and examples than by the development of mathematical proofs".
