Jerry Reinsdorf

He ranked a lofty No. 5 on last year’s list. But that was before the Bulls and the White Sox, the cornerstones of Reinsdorf’s estimated $1.2 billion fortune, started to show cracks. The Sox tanked despite a roster of many of the best-paid players in town, and the Bulls—well, you know how that ended. One … Read more

Dennis Muilenburg

He may be new to the corner office (as of July), but not to Boeing: Muilenburg started working at the aerospace giant as an engineering intern back in 1985. So far, he’s had a few wins (for example, reaching a union contract deal) and a few stumbles (Boeing stock fell 15 percent in the January … Read more

Mellody Hobson

Don’t call her George Lucas’s wife. The only Chicagoan to land on Time magazine’s 2015 list of the 100 most influential people—alongside the likes of Apple CEO Tim Cook and the infamous Koch brothers—Hobson is, of course, a major power in corporate America: She’s president of Ariel Investments and on several blue-chip boards (Starbucks, Estée … Read more

Zach Fardon

Chicago’s storied history of corruption tends to keep its U.S. attorneys busy, and Fardon certainly isn’t getting shortchanged. His office recently nabbed former U.S. House speaker Dennis Hastert and on-the-take ex–CPS chief Barbara Byrd-Bennett; it was the first in the nation to drop the hammer on a “spoofer,” a trader who cheated millions of small … Read more

George Lucas

The Force is definitely with Lucas. He’s worth billions. He’s got a powerful, glamorous wife (No. 18). A new baby. And an old baby, Star Wars, that was, of course, just reinvigorated by director J.J. Abrams and smashed box-office records around the world. (Lucas consulted on the film.) New interest in the Star Wars series … Read more

Neil Bluhm

Bluhm has struggled with union headaches lately, and his upscale Rivers Casino in Des Plaines ended a four-year growth streak last year. But it’s still the most profitable casino in Illinois. And Bluhm shows no signs of slowing down: The art lover was recently elected a board cochair of New York’s prestigious Whitney Museum of … Read more

Irene Rosenfeld

The past year can’t have been much fun for Rosenfeld, thanks to pressure from major investors Nelson Peltz and William Ackman that led to intense cost cutting. But it paid off: Mondelez stock rose 23 percent in 2015, handily beating both its industry peers and the S&P 500. Her next tasks are to goose growth … Read more

Theaster Gates

Leave it to Gates to steal the show during the inaugural Chicago Architecture Biennial last summer. Despite a star-studded roster of 150 architects from around the world—David Adjaye and Steven Holl included—Gates was the talk of the town, thanks to the opening of his $4.5 million Stony Island Arts Bank ([[[see page 48]]]), by far … Read more

Mary Dillon

Dillon’s three years at the helm of the Bolingbrook-based retailer have been a thing of beauty. Ulta’s current 860 stores? Dillon wants 1,200. Ulta has hired more than 5,300 people to staff the hundreds of stores she’s already opened. Among her fans: Starbucks, which recently asked her to join its board.

Dick Durbin

Now in his fourth term, Durbin is the second-longest-serving U.S. senator in Illinois history. The liberal lion enters 2016 with a few choice items on his bucket list—stricter gun control as well as immigration, criminal justice, and higher-ed reforms—and plenty of fire in his belly. Many political oddsmakers bet on the Democrats recapturing the Senate … Read more
