When you walk onto the trading floor of the NYSE with Mickie Siebert, it feels a bit like being in the presence of royalty. People recognize her and want to say hello. And being with Mickie reminds you of the days before computer trading, when everything happened on the trading floor in a flurry of activity, when tourists could gaze down from the balcony, before 9/11 forced it to close. Mickie Siebert didn't set out to make history as the first woman with a seat on the NYSE. She was supporting her family after her father died. She needed to make money.Working for herself looked like the best way to manage that in 1967. She has grown into her role in history since then. When she's approached on the sidewalk, walking down Wall Street, she is always courteous and interested. But you can tell that beneath her gracious exterior, she's still tough as steel. Mickie Siebert is someone you'd always want on your team, whatever the challenge.
