Alexander Stewart (September 12, 1829 – May 24, 1912) was a Scottish American immigrant, lumberman, Republican politician, and pioneer settler of Wausau, Wisconsin.

He had no grandchildren, so the bulk of his estate went to the Alexander and Margaret Stewart Trust, which has provided more than $125 million in grants for research on cancer and pediatric diseases.

His elder brother and business partner, John Stewart, also became a millionaire through their work and served in the Illinois House of Representatives.

[1] The area was heavily forested, and Stewart learned about logging and rafting timber in his teenage years.

[4] According to his obituary, Stewart personally cut down the pine trees in the area that is now the Wausau downtown square.

In their earlier years, they formed a close friendship with Walter D. McIndoe, and frequently cut their lumber at his mill.

[2] John Stewart eventually left Wisconsin and settled a farm in Illinois, though he maintained his share of ownership in their business.

[4] By the time of his death, they owned or had significant interests in lumber-related companies in Michigan, Arkansas, California, Minnesota, Indiana, Nebraska, Colorado, Iowa, and Ontario.

[1] His biography suggests that he was finally comfortable running for office after the appointment of Walter Alexander as secretary and treasurer of his company.

Stewart faced a difficult challenge for the nomination, opposed by former lieutenant governor Sam Fifield and former state senator Merritt C.

[12][13] In the Spring of 1900, Stewart announced that he would not run for a fourth term, saying that he wanted to return his attention to his business interests.

Both of Stewart's parents were born in Scotland, they also emigrated from Canada to the United States, settling in Kane County, Illinois.

Their youngest daughter, Helen, married United States Army general Daniel Bradford Devore.
