Beginning in the 1920's and on into the 1940's Miss Cottrell is listed as the author of articles and booklets on education techniques and late in the 1940's as a coauthor on an education article with future Stockton principal John Thomas Greenan. One of her booklets lists her birth year as 1893.
According to a 1956 (in Vols 36-37) issue of Safety Magazine, Miss Cottrell had just passed away. The article stated that she had still been a teacher at Stockton when she retired and that, before her final illness. she had been operating a gift shop in Basin Harbor, Vermont.
A July 1, 2011 post lists some teachers who served with Miss H Louise Cottrell in the 1930's.
