- Description
- Doing the calculations associated with tax collection has inspired inventors from at least the 1600s, when the French mathematician and philosopher Blaise Pascal invented an adding machine for that purpose. In 1879 Robert Levin Mudd (1837–1910), the county clerk in Bond County, Illinois, patented this tax calculator. It has sliding tables for calculating the tax due on property worth up to $10,000, at rates of 3 cents, 5 cents, and 25 cents per $100 value. Other columns give the total tax due if assessments are made at several rates for different projects. The instrument folds and fits neatly into a wooden case. This example is incomplete. Compare to U. S. patent 213234, dated March 11, 1879.
