I think the modern speedometer was invented or perhaps perfected by John O'Brien, an engineer at the Waltham Watch Company in the 19 teens.
The most often cited inventor of the first speedometer is Josip Belusic. A Croatian college professor and inventor, he developed it in 1888 and called it a velocimeter in his patent.
