The following was submitted in September of 2006 by her nephew Ben Hiebel:
She was born on June 26, 1879 in New Hope, Wisconsin. Adelaide was a self styled artist who was not satisfied with her art ability, so she went to study at the Art Institute of Chicago. There she met Zula Kenyon, who became her teacher and mentor.
She taught in the art department of Ohskosh College around 1916, but upon Kenyon's recommendation, attained a position at the Gerlach Barklow Calendar Company and relocated to Joliet, Illinois around 1918.
She married once, but it seems her husband did not keep good company, and was killed shortly after the marriage, and her family never even learned his real name. She never remarried.
Hiebel was an eccentric, successful artist and became known for her lavish parties. Her paintings brought as much as $10,000 each, and she attracted artists from across the nation to her annual artists' Open House and Gathering.
Adelaide worked for Gerlach-Barklow for over 40 years, completing more than 400 known signed or documented works, including portraits of the CEO's, and a pastel of Lois Delander of Joliet, crowned Miss America, in a bathing suit.
Of all her works, only 50 originals are documented today. She purchased her favorite originals from the company upon her retirement to California in 1955. Adelaide Hiebel passed away in 1965 at her home in Santa Ana, California. The family was not able to locate any of the originals paintings she took along at the time, some of which have been located by collectors since then.
