H. Vandervoort (Harold Vandervoort) Walsh

Harold Vandervoort Walsh was an American author born in 1892. He is credited as the author of The Construction of the Small House (1923), a detailed guide for people planning to build modest homes.

Contemporary editions of that book identify him as an instructor of construction in the School of Architecture at Columbia University, and note that the volume included illustrations by the author. The book focuses on practical topics like building methods, materials, plumbing, heating, roofing, and financing, aiming to make technical knowledge easier for non-specialists to use.

Walsh also wrote Understanding Architecture (1934), suggesting a broader interest in explaining architecture clearly to general readers and students. Reliable biographical details beyond his birth year are limited in the sources I could confirm, so many parts of his life remain obscure.
