"Who" is in the subjective case; it should be used when it is the subject of the clause.

"Whom" is in the objective case; it should be used when it is the object of the clause or of a preposition.

John is the man who introduced me to my wife. (who = subject)
John is the man to whom I was introduced. (whom = object of preposition "to")
Mary is the woman whom I love. (whom = direct object of "love")
