Gardner Whitman Pearson (September 4, 1869 – June 23, 1953) was an American military officer and politician who served as Adjutant General of Massachusetts from 1911 to 1914 and 1916 to 1917.

[3] In 1894, based on the recommendation of Congressman Moses T. Stevens, president Grover Cleveland appointed the 24-year old Pearson to the position of Lowell postmaster.

The law was challenged by Foss' successor, David I. Walsh, but it was upheld by the Massachusetts Supreme Judicial Court.

[6] In 1914, the state legislature eliminated the term of office and Walsh removed Pearson and retired him with the rank of brigadier general.

[8] In 1917, with the United States' entry to World War I looming, McCall sought to make the business and military sides of the Massachusetts National Guard distinct.
