author
Known today mainly for a single surviving technical paper, this early-20th-century writer left a compact but intriguing mark on engineering literature. His work focuses on the practical problem of pipe expansion and shows the clear, methodical style typical of professional engineering writing of the period.

by Ralph C. Taggart
Very little biographical information about Ralph C. Taggart could be confirmed from reliable online sources during this search. What is clear is that he is credited as the author of "Expansion of Pipes," a paper published in Transactions of the American Society of Civil Engineers, vol. LXX in 1910.
Modern library and ebook records, including Project Gutenberg, preserve that work and identify him simply as "Ralph C. Taggart." Based on the publication venue and subject matter, he appears to have been connected with civil or mechanical engineering practice, writing about the stresses and movement involved in steam-pipe systems.
