Why This Person Is Included
Thomas W. Stewart patented the string mop with a removable wringing device in 1893 — the practical floor cleaning tool that replaced bulky rag mops in commercial and industrial settings. The mop is in every school, hospital, and restaurant. Stewart's name is not.
Historical Significance
Stewart's mop with an integrated wringing mechanism made floor cleaning significantly more efficient in commercial settings — eliminating the need to ring out a heavy rag mop by hand and enabling faster, more hygienic floor maintenance.
The Story
Thomas W. Stewart received U.S. Patent No. 499,402 in 1893 for a string mop with a removable wringing device that allowed users to squeeze out dirty water without touching the mop head. The design made commercial floor cleaning significantly more efficient and hygienic than existing rag mop methods. His biography beyond the patent is not documented.
