Judy Marks, CEO, Otis Elevator
There are only 36 women leading Fortune 500 companies. While that’s the largest number of female C-E-Os ever, it’s still a small percentage of the total. However, that number will likely grow by at least one later this year. Otis Elevator is set to spin out of United Technologies where it has been a subsidiary for the past four decades. With almost 13 billion in revenue, it should have no trouble finding a home on the 500. Judy Marks is President and C-E-O of Otis.
