born in 1809, a descendant of Governor Winthrop, was graduated at Harvard in 1828. He was a Whig in politics, and was Speaker of the Massachusetts House of Representatives. From 1841 to 1850 he represented his State in the lower House of Congress, where he acquired a reputation as a debater and orator. He was Speaker of the House in 1847-18491 and was defeated in 1849 for re-election to the chair. In 1850-1851 he was U. S. Senator, but a coalition of Democrats and Free-Soilers defeated him. The same year he failed as the Whig candidate for Governor. Winthrop received a plurality of votes, but as the law then required a majority the choice went to the legislature, where he was beaten. Mr. Winthrop has long been noted as a classic orator, particularly on historical themes. His addresses on anniversary occasions, as at the Yorktown Centennial in 1881 , were greatly admired. He wrote a life of John Winthrop.
