Thomas Alexander Sperry (July 6, 1864 – September 2, 1913) was the co-founder and the "S" of S&H Green Stamps, together with Shelley Byron Hutchinson of Ypsilanti, Michigan.

"[4] Sperry died in New York City at the age of 49 years on September 2, 1913, of ptomaine poisoning contracted during the return voyage after a two-month trip to Europe.

[6][7][8] Thomas Sperry was involved with real estate businesses and died in Palm Beach, Florida, in 1973.

The stamps gained popularity during the early 1900s as the S&H program offered incentives to shoppers, rewarding them for making timely payments in cash, helping to maintain customer loyalty to participating merchants.

Hutchinson alleged that he had been cheated out of $5 million as a result of secret dividends that diverted company funds to Sperry.
