Professor Mirsky worked at a college. In a timeline in which Emily Rutherford and Tom Charrington separated as teenagers, he never worked with Professor Henderson. Instead, he worked in weapons research and invented a deadly gaseous weapon called Close Gas. When the Third Doctor encouraged Emily and Tom to stay together, the timeline was averted, Mirsky worked with Henderson, and the weapon was never invented. (PROSE: Separation Day)
