Woolgrower and Boise Business Executive Thomas McMillan [otd 02/25]

Sheep rancher and later Boise investor/manager Thomas McMillan was born February 25, 1865 in Scotland. As a young teenager, he worked in a Glasgow bank. His older brother John came to the United States in 1881, and their father brought the rest of the family over a year later.

Thomas followed John west and herded sheep in Wyoming for a while. Then, around 1886, the brothers each settled down near Corder Station, located about twenty miles southeast of Boise. When John became postmaster at the station, he persuaded the Post Office to call the place Mayfield, after an ancestral home town in Scotland.

For the next thirty years, the McMillan Sheep Company was a major wool producer for Idaho. In 1893, John played a prominent role in the creation of the Idaho Wool Growers Association. Thomas was not among the Charter Members, but he soon joined the organization. Both brothers served terms as president of the Association.

In 1897, Thomas married Roxie Corder, daughter of the pioneer operator of Corder Station. He then began to spend more and more time in Boise. With the sheep company prospering, the brothers were looking for other promising investments. One such project turned out to be a new luxury hotel to replace the famous, but antiquated Overland Hotel in the heart of downtown. The brothers teamed up with two other sheepman, one related by marriage. None of them knew anything about the hotel business, so a fifth investor was a man who had helped operate the Overland.

Construction of what they called the Idanha Hotel took about ten months and on, January 1, 1901, the investors hosted a private opening for friends and family. Two days later, they let the general public in. (The Overland was torn down in 1904 and replaced with an office building.)

As president of the Idanha Company, John moved permanently into Boise after the hotel opened. Thomas, however, split his time between Boise and Mayfield for about the next decade. Still, in 1906, he was among a group of investors who bought a majority interest in the Boise National Bank. He became an active Director of the bank.

By the spring of 1910, Thomas had moved his entire household to a residence about two blocks north of the Idanha. Three or four years later, he began a long tenure as the Secretary-Treasurer of the Idanha Hotel Company. Then, in 1915, he added a Director’s position with the Boise Stone Company to his duties. A couple years later, he withdrew from any active role in the sheep business. By early 1920, he was managing the main quarry for the Stone company. It’s not clear how long that lasted, but he was still loosely associated with company almost two decades later.

Thomas was a Vice President for the Boise National Bank from 1923 through 1932. After that, he became more involved with the Idanha company and eased out of an active role with the bank. Thus, when brother John died in 1936, Thomas took his place as president. He and Roxie also moved into a suite at the hotel. Thomas would remain president until his death in September 1953.

However, around 1940, when Thomas was in his mid-seventies, he brought his oldest daughter, Mrs. Roxie (McMillan) Johnson on board as Vice President and manager of the Idanha. Having assumed a major management role in the late Forties, she sold the hotel in 1962. Listed on the National Register of Historic Places, the Idanha has since been converted to apartments and small shops.
