author
An early 20th-century writer remembered chiefly for a concise biography of Giacomo Puccini, he wrote about the composer while Puccini was still at the height of his career. Very little biographical information about him appears to be widely documented, which gives his surviving work an especially archival feel.

by Wakeling W. Dry
Wakeling W. Dry is a little-documented author associated with music writing in the early 1900s. Public-domain library records connect him with Giacomo Puccini, and LibriVox lists him as active around 1906.
His best-known surviving work is Giacomo Puccini, a short biography that introduces readers to Puccini's life and discusses operas such as Le Villi, Edgar, Manon Lescaut, La Bohème, Tosca, and Madama Butterfly. Because it was written during Puccini's lifetime, the book offers a contemporary view of a composer who was still making his reputation.
Beyond that, reliable biographical details about Dry are scarce in the sources I could confirm. For modern readers, that makes him one of those intriguing figures whose legacy rests mainly on a single useful, period piece of music biography.
