Roswell Pettibone Flower was the 30th Governor of New York from 1892 to 1894.
He was a son of Nathan Monroe Flower and Mary Ann Flower, the sixth of nine children.
In 1853, he became Deputy Postmaster of Watertown, New York, at a salary of $600 a year, and after six years had saved $1,000 and opened with a partner a jewelry store. Two years later, he bought his partner out, and continued in this business until 1869.
In 1869, Henry Keep, a former President of the New York Central Railroad, was dying and asked Roswell Flower, whose wife was a sister of Keep's wife Emma, to manage the $4,000,000 estate for his widow. Flower asked Keep for guidance on who he could trust, and named a business associate, Daniel Drew. Keep replied, "He is as honest a man as there is in the State of New York, but for fear that somebody else will cheat, he will always begin first." The business brought Flower to New York City where he became known as a shrewd financial administrator, and opened the banking house of R. P. Flower & Co.
He was elected as a Democrat to the 47th United States Congress to fill the vacancy caused by the resignation of Levi P. Morton upon his appointment as Minister to France, and served from December 5, 1881, to March 3, 1883. He was also elected to the 51st and 52nd United States Congresses, and served from March 4, 1889, to September 16, 1891, when he resigned upon his nomination for Governor.
