|First appearance||Mars University|
|Voiced by||Billy West|
The 20th century lecturer is a professor of 20th century studies at Mars University. He teaches a class that contains Fry, Amy, and Guenter, assuring them that the only way to get an A is to have actually lived in the 20th century. He does not hesitate to electrocute students when they say or do something wrong. The character appears to owe something to Professor Charles W. Kingsfield, Jr., John Houseman's character in The Paper Chase, set in Harvard, the Mars University of Earth.
