Usage
It was formerly considered correct to use whom whenever the objective form of who was required. This is no longer thought to be necessary and the objective form who is now commonly used, even in formal writing: there were several people there who he had met before . Who cannot be used directly after a preposition – the preposition is usually displaced, as in the man ( who ) he sold his car to . In formal writing whom is preferred in sentences like these: the man to whom he sold his car . There are some types of sentence in which who cannot be used: the refugees, many of whom were old and ill, were allowed across the border
