1. Mary Callahan Erdoes

CEO, JPMorgan Asset Management

Mary Callahan Erdoes is grateful for the technology that gives her the flexibility to work from anywhere, but she wouldn't mind the occasional blackout zone.

"I thought it was the worst thing when they created WiFi on overnight European flights," jokes the head of JPMorgan Chase's asset management division. "It was my last spot of sanity."

Of course, working on planes, trains and automobiles is de rigueur for the woman who oversees the management of $2.4 trillion in client assets at the country's largest banking company. Since assuming her role in 2009, Erdoes has made asset management a reliable warhorse atJPMorgan, generating 11% of the company's annual revenue and net income in 2013.
