Dormitzer was born in Prague, Czech Republic on May 5, 1830. She emigrated to the United States arriving in New York at the age of 20 years in 1850. She married her husband, Henry Dormitzer the same year and they settled in Hoboken, New Jersey where Henry made his fortune in the tobacco business. After retiring the couple moved to New York City where they were both became active in politics. Dormitzer was a suffragette, a member of the National-American Woman Suffrage Association and the Sorosis Society.
Professional career[edit]
While the Dormitzers were rich enough that they could afford to hire servants to do household tasks such as cleaning windows, Anna Dormitzer was sensitive to the precarious dangers of cleaning, particularly window-cleaning so much so that starting in 1878, she registered twelve patents for a variety of window washing devices. These included chairs and stepladders and a combination of both. Dormitzer included very precise and detailed drawings with her applications since all but her first application included a model.[2][3]
