What it is

The first working parking meter, nicknamed the 'Black Maria', was installed on the streets of Oklahoma City on 16 July 1935 to regulate timed on-street parking downtown; lawyer and publisher Carl Magee drove the project and patented the design in 1938.

Wikidata credits only Carl Magee, but the technical design was done by engineers Holger Thuesen and Gerald Hale, professors at Oklahoma State University, at Magee's request; Magee patented and promoted the system.

What it led to

  • Municipal regulation of timed parking
  • A new source of municipal revenue
  • Industrial production of parking meters from 1936
