The Captains of Industry lecture series at the 92nd Street Y welcomed Yahoo! CEO Carol Bartz and Bloomberg Businessweek chairman Norman Pearlstine earlier this month, and Bartz spoke about her college years, writing code on an IBM 1620 in 1967, working for 3M (she was fired before starting work due to allegations that she slept with her boss), Groupon’s valuation, employee turnover at Yahoo!, and the lack of probability of a merger between Yahoo! and Aol.
