Few opera stars have led such an impressive career. For over a quarter of a century, her coloratura voice captured the stages of Paris, London, Buenos Aires, Mexico, and the United States. Like Mario Lanza and Luciano Pavarotti, she acted in second-rate films about opera stars, which were surprisingly well-attended. As a child, I recall her appearances on variety shows and heard her on the radio at least once a month. Today, there is a Lilypons, Maryland (and its main street, Lily Pons Rd.). Even a contemporary rock group has named itself after her. She was the Three Tenors of her day.

Her sweet soprano voice had an extremely high tessitura. It was said she could hold a high D for about a minute. The Metropolitan Opera revived roles especially for her, like Delibes’ Lakmé, Donizetti’s La Fille du Regiment, and Rimsky-Korsakov’s Le Coq d’or.

In addition to her fabulous voice, Pons had another distinction — having a Maryland post office named for her. In 1932, the tiny Frederick County post office of Lilypons opened for business. “It was a dot on a map, because nobody has ever been quite sure what to call it. Lilypons, Md., was never a city, town or even a hamlet,” said The Evening Sun in 1986. “It is now what it has always been: one frame building surrounded by a small cluster of ponds nestled into a peaceful crook of the Monocacy River eight miles south of Frederick. Its only inhabitants have been rare goldfish and beautiful blooming waterlilies.” In 1963, during a period of cost cutting, the Postal Service discontinued the Lilypons postmark and combined its functions with the nearby Buckeystown post office. A plaque commemorating the tiny post office was mounted on the building in 1986.
