Chávez had evidently met former U.S. congresswoman, ambassador, publisher, playwright, and journalist Clare Boothe Luce in Florence at some point in the late 1940s. An unlikely friendship sprang up between them, which continued for nearly three decades. In February 1950 Luce came to Mexico City for a week of cultural exploration, and on 18 February 1950 wrote on a scrap of newspaper a commission for a musical work (initially envisioned as a piano concerto), "for Ann Clare Brokaw the most beautiful and sad and gay thing you ever wrote that has her lovely face and my broken heart in it". Brokaw, who had died as the result of an automobile accident in 1944 at the age of nineteen, was Mrs. Luce's only child, from her first marriage.
