From Wikipedia:
"Just two months before his death, at age 95, he appeared on the February 9, 1956 episode of the CBS TV quiz show I've Got a Secret as a mystery subject, in an episode in which Lucille Ball made an unusual appearance as a guest panelist. Seymour incorrectly gave his age on the show as 96, although his 96th birthday was actually not until March 28, several weeks later. Seymour died at the home of Mrs. Irene (Horn) Hendley, his daughter in Arlington, Va. He had been in failing health since February when he fell in a New York City hotel while preparing to appear on "I've Got A Secret". He came on the show with his left eye swollen. Garry Moore had suggested he not appear, but Seymour insisted. In the episode, he was initially questioned by Bill Cullen but it was Jayne Meadows who guessed Seymour's claim to fame. Moore generously awarded Seymour the $80.00 he would have won had he stumped the panel, and a can of Prince Albert pipe tobacco rather than the usual prize of a carton of Winston cigarettes (Winston was the show's sponsor, but Seymour did not smoke cigarettes).
Samuel J. Seymour, who made his home in Baltimore, MD, for many decades, where he worked as a carpenter and contractor, was survived by five children, 13 grandchildren and 35 great-grandchildren. He was interred at Loudon Park Cemetery, in Baltimore, MD.
Seymour died 15 days after his 96th birthday, three days shy of the 91st anniversary of the Lincoln assassination, and 63 days after his appearance on I've Got A Secret."
