It's February 14, and on this day in 1964, Elvis Presley made a grand philanthropic gesture by donating the retired presidential yacht, the USS *Potomac*, to entertainer Danny Thomas for use by St. Jude's Hospital. Known as the “Floating White House” during Franklin D. Roosevelt’s presidency, the vessel became a symbol of Elvis’s growing commitment to charity and public service. The high-profile donation showcased his support for children's health and medical research, leaving a legacy that reached far beyond music.
