Bott's Dotts // Dr.Elbert Dotts

Road dots: Ever wonder what you call those fluorescent dots down the center of the highway? They're called Bott's Dotts, named after Dr.Elbert Dotts, a chemist with the California Department of Transportation, who invented them.

Naming the dots Bott's Dotts when the inventor is named Dotts had me puzzled, so I googled and found out that the above is wrong, wrong wrong. The inventor's name was actually Elbert Botts, and the dots are called Botts' dots. Also, a space is required between Dr. and Elbert.
