Stales has it right that Hoboken is a place; it's a city in northern New Jersey, just across the harbor from New York City and noted as being the place where Alexander Hamilton was shot by Aaron Burr. (At that time, Hoboken was a remote suburb where one could have a duel in privacy.)

"Hoboken numbers" are classification numbers given to the works of Franz Josef Hayden, named after the first editor/collector of his works, some unknown-to-me Herr Professor Hoboken (Musik -- any light on this?) and, as such are like the "K. nos." given to the works of Mozart, such as the Piano Concerto No. 21, K.467. K. stands for Koechel, the first editor/collector of Mozart. The work of Johann Sebastian Bach is generally classed by BWV numbers, but that is no one's name; it stands for "Bachwerkverein" the standard edition of the collected works of JSB.
