With New York City focused on the question of what it takes to be an effective school system leader for the 21st century, the Times published profiles of four respected superintendents in this Sunday's Education Life section: Alan Bersin (San Diego), Carmen Russo (Baltimore), Joseph Olchefske (Seattle), and Barbara Byrd-Bennett (Cleveland). Two come from nontraditional backgrounds - one was a U.S. attorney, and one was an investment banker - and two came up through the education system, but all four seem to share a no-nonsense approach and a tireless devotion to a 24-hour-a-day job.
