Need help with word puzzle

Sorry to bother you, but I have been doing cryptograms for years and almost always get them. This one has totally stumped me and if anyone has free time, at least give me what the H and T are supposed to be. Thank you.

Hmm. If you decrypt the ciphertext “WMHJ DCVUBN. WTGAY DCVNQWBN. WMHJ YBWVBN AU HCTUHB, WTGAY AU HCTYTHQBY.”, you get

LUCK WHINES. LABOR WHISTLES. LUCK RELIES ON CHANCE, LABOR ON CHARACTER.

so I guess the answer is

Richard Cobden
