Built in 1887–1889 in the Queen Anne style, the Hume House served the Thomas Hume family through four generations. Its architect, like that of the Hackley House, was David S. Hopkins of Grand Rapids, and the structure behind the two houses was shared by both families. Known as the City Barn, that building reflects features of each house. Although larger than the Hackley House, the Hume House is less pretentious in detail. One hundred years after its completion, the Hackley & Hume Historic Site was administered by the Muskegon County Museum. Thomas Hume, born in 1848 and dead in 1920, was Charles H. Hackley’s business partner from 1881 to 1905. An Irish immigrant, he came to Muskegon in 1872 and began working as Hackley’s bookkeeper. After Hackley’s death, Hume was instrumental in transforming Muskegon from a lumber town into a major manufacturing center. At his death in 1920, he was serving as an officer of the Amazon Knitting Company, Shaw Electric Crane Works, Sargent Manufacturing Company, Chase-Hackley Piano Company, the Stand Maleable Company, and the Hackley National Bank.
