Lou died May 13, 1962, of renal failure, in South Burlington, Vt. He was 75. Raised in Tegucigalpa, Honduras, where his family owned "El Rosario Mining company", he moved to the US in 1898 and prepared at Lawrenceville , where he displayed outstanding talent in literature and tennis (he later became Central American tennis champion).

At Princeton Lou collaborated in writing the book and lyrics for the Triangle Club show “Any Moment Now”. Having dropped out after junior year, he engaged in playwriting and published his first book of poems, “Of Mute Insensate Things”, in 1911. Lou returned in 1914 to study journalism and finish college. The following year he published “Days of Dust”.

In 1921, after his father died and Lou returned to Honduras to run the family business, he married Maria Dolores Solorzano. They raised three boys and three girls. These endeavors left little time for the "speculative pursuit of writing plays." To that, other literary activities, and his family, Lou devoted full time after retiring in 1952.

Lou's family (Maria, their children and 16 grandchildren) loved him deeply as a "wonderful husband and father."
