B. Platt Carpenter

Carpenter was born in Stanford, Dutchess County, New York. He graduated from Union College in 1857, and studied law. He was admitted to the bar and practiced in Poughkeepsie, New York. On November 24, 1860, he married Esther Thorn, and they had three children.

Carpenter was District Attorney of Dutchess County from 1864 to 1869; a delegate to the New York State Constitutional Convention of 1867-68; a delegate to the 1868 and 1884 Republican National Conventions; a member of the New York State Senate (11th D.) in 1876 and 1877; and Judge of the Dutchess County Court from 1878 to 1882.

At the New York state election, 1882, he ran for Lieutenant Governor of New York on the Republican ticket with Charles J. Folger, but they were heavily defeated by Democrats Grover Cleveland and David B. Hill.

In December 1884, he was appointed by President Chester A. Arthur as Governor of the Montana Territory, and on December 31, 1884, he left Poughkeepsie for Helena, Montana. After a short tenure, he was removed from office by the new Democratic President, Grover Cleveland, but he stayed in Montana, and was a delegate to the Montana State Constitutional Convention of 1889.

On December 24, 1921, Carpenter died in Chula Vista, San Diego County, California. He was buried at Poughkeepsie Rural Cemetery.
