author
Best known for a practical early-20th-century guide to decorative concrete work, this coauthor helped show how cement could be turned into tiles, pottery, garden pieces, and other handmade designs. The surviving record is sparse, but the book remains a small window into Arts and Crafts–era making.

by Pedro J. (Pedro Joseph) Lemos, Reta A. Lemos
Reta A. Lemos is known today as the coauthor, with Pedro J. Lemos, of Color Cement Handicraft. Project Gutenberg lists that title under her name, and library and bookseller records identify it as a 1924 work published by The Davis Press in Worcester, Massachusetts.
The book focuses on creative, accessible uses of colored cement and concrete, including decorative tiles, pottery, garden ornaments, and architectural details. Its practical tone suggests it was written for makers, teachers, and students interested in hands-on craft rather than theory alone.
Little biographical information about her was easy to confirm from reliable online sources, so a fuller life story remains unclear. Even so, her name endures through a distinctive craft book that continues to circulate in reprints and digital editions.
