kottke.org digs up a New York Times editorial from 1920 that pooh-poohs the very idea that a rocket could function in space, ridiculing Robert Goddard saying he lacks “the knowledge ladled out daily in high school.”
In 1969, 49 years (!) later, they issued a correction:
Further investigation and experimentation have confirmed the findings of Issac Newton in the 17th Century and it is now definitely established that a rocket can function in a vacuum as well as in an atmosphere. The Times regrets the error.
