In a Jan. 20, 1853, article, the Times misspelled Solomon Northup’s surname as Northrop and as Northrup.

The Times corrected Northup’s name on Tuesday, after the errors were pointed out by someone looking at its archives.

Northup was born in New York and was kidnapped and sold as a slave in 1841. He spent the next dozen years in Louisiana before regaining his freedom.

“12 Years a Slave” won the Oscar for best picture at the Academy Awards on Sunday. It starred Chiwetel Ejiofor as Northup.
