(born c 1866, who worked in a printing office). LaCroix never married and died at her home at 5726 McPherson Avenue, Saint Louis, Missouri from Myocarditis, a condition she had been suffering from for a number of years. Librarian Gilbert Witte has catalogued LaCroix"s Old and New Designs craft series, which was published by the Saint Louis Fancy Work Company in the early decades of the 20th century.
First edition copies are now part of the collection of the Tennyson Library of Crochet & Related Arts, part of the University of Illinois Rare Books & Manuscripts Library.
Quilt historian Barbara Brackman writes that LaCroix"s 1915 book of quilt patterns Martha Washington Patchwork Quilt Book "captured the cultural confusion American needleworkers faced" and was one of the few that "attempted a new recipe for the American melting pot".
