After receiving his education, Smythe came to New York in 1836 and clerked in one of the "large jobbing and importing houses" that was formed in 1839,[6] later becoming a partner and then joining the Boston commission house of F. Skinner & Co. in 1846,[6] remaining until 1857.[4][1] In 1856, while traveling in a carriage from Bern to Basel in Switzerland, Smythe met and befriended novelist Herman Melville, who he later secured a job for as an inspector of customs when Smythe was the Collector of the Port of New York.[2]

He was originally a Whig in politics, then a Republican, and is a thorough Union Man".[8]
He is most well known for his impeachment in March 1867, which accused him of corruption and,[9] with a resolution for his removal of office from the House, was ultimately ignored by President Andrew Johnson. Smythe left office in 1869, after a change of administration.[10]
