John Van Nostrand was born in Newark, New Jersey back in 1872. Sorry, but I don’t have any information about him until he started working for Thomas Edison. He attended Rutgers University obtaining a B.S. in chemistry in 1894.
One of his major contributions was the development of the “classifier”. It’s a machine which is used for the separation and chemical treatment of fine solids suspended in liquid. You can find his invention which is used for the treatment of sewage and water purification. While his invention has been improved the basic concept is still in use to this day.
Another idea came to him in the early 1950’s. He postulated that at night when it was raining, snowing or fog impaired one’s vision it was due to the people using the white lines painted in the middle of the highways for guidance. He convinced the engineers in Westchester County, New York to test his theory and it worked. So, the next time you are driving and wondering who came up with the idea to paint the white lines along the outside shoulders of the highway, now you know it as John Van Nostrand Dorr.
