From the Lawrence Daily Journal-World for May 30, 1987:

Longtime public servant Frank Carlson, 94, had passed away today in Concordia, Kansas, after an extended hospitalization. The former U.S. Senator was the only Kansas politician to have held the three offices of senator, governor, and congressman. Carlson’s unpretentious manner and unassuming style had given him a close rapport with ordinary Kansans and had aided him in his 13 election victories in 13 tries from 1928 to 1962. He had retired at the age of 74 after 40 years of public service, saying that it was his desire “to have the same opportunity to enjoy the same privilege most of you here now enjoy: that of being a private citizen in our great state of Kansas.” He had then retired with his wife Alice, whom he had married in 1919, to his 500-acre family farm near Concordia, where he could be seen for more than another decade driving a tractor, plowing a field, or baling hay.
