Many people come to Minnesota for treatment at the famous Mayo Clinic in Rochester, and surgeons at the Univ. of Minnesota have won recognition for their development of new heart-surgery techniques. The Minnesota Symphony Orchestra is nationally known, and the Tyrone Guthrie Theater in Minneapolis houses an excellent regional repertory company. Minnesota has contributed important literary figures to the nation, including Sinclair Lewis, F. Scott Fitzgerald, and O. E. Rølvaag. Economist Thorstein Veblen and aviation pioneer Charles A. Lindbergh were also born in the state.
