Granot Loma is an estate located on County Road 550 north of Marquette, Michigan, constructed in the tradition of the Great Camps of the Adirondacks in the late 19th and early 20th centuries. It was listed on the National Register of Historic Places in 1991. It is said to be the "biggest log cabin in the world" and the most expensive residence in Michigan.

Louis Graveraet Kaufman was an American business executive and businessman. He was named president of First National Bank of Marquette in Marquette, Michigan in 1906. In 1910 he became the president of Chatham National Bank of New York, also remaining president of First National. Under Kaufman, Chatham National soon merged with Phenix National to form the Chatham Phenix National Bank and Trust Company. By the time Kaufman retired in 1932, the bank had increased 50-fold in size. Joining General Motors's board of directors in 1910, Kaufman remained on GM's board for 22 years, and was chairman of their finance committee.
