The Adorno traffic light is a traffic light artefact located in Frankfurt and named after Theodor W. Adorno.^[1] It has become one of Frankfurt's landmarks. The traffic light is on Senckenberganlage, a street which divides the Institute for Social Research from Goethe University Frankfurt. Adorno requested its construction after a pedestrian death in 1962, and it was finally installed 25 years later.^[2]

In 1951 the Institute for Social Research moved into a new building on Senckenberganlage.

On March 12, 1958, Adorno wrote a letter to the University outlining dangers of crossing the street, which led to police chief Gerhard Littmann marking a pedestrian crossing.

On November 29, 1961, Adorno demanded "a bridge for pedestrians over the Senckenberganlage or a diversion of all traffic".

In 1962 a person was killed in a traffic accident in the Senckenberganlage area, which led to Adorno writing to the Frankfurter Allgemeine Zeitung demanding "traffic lights in the whole university area":

“When crossing the Senckenberganlage, near the corner of Dantestrasse, one of our secretaries was run over and seriously injured after a passer-by had had a fatal accident at the same place a few days earlier. On the way to university you have to run across the street in an unworthy manner as if you were running for your life. Should a student, or a professor, find himself in the state that is actually appropriate for him, namely in thought, then there is an immediate threat of death. "

- Theodor W. Adorno

Adorno's demand was fulfilled 18 years after his death. In 1985 Jürgen Habermas (director of the institute) campaigned for the traffic lights. In 1987, Habermas' successor, Ludwig von Friedeburg, placed a pedestrian traffic light at the Senckenberg plant. The light was named the "Adorno traffic light".^[3][4][5]

The Adorno traffic light has developed into a tourist attraction in Frankfurt.^[6]
