Finally, I want to say just a few words about Alan, the man. Going back as far as 1983, when Alan, Nancy, and their little girls came to a birthday party I was giving for my wife, Ellen, in Vienna, I have only the most positive impressions of Alan as husband, father, and sibling. At that birthday party, a tiny Lindsey had brought an even tinier glass snowball containing the Ferris wheel from Vienna's great park, the Prater. At the last moment, she became distraught at the idea of having to give up what seemed to her to be a magical object. Alan insisted, but then spent the next 10 minutes gently consoling his little daughter before joining the festivities. Nancy and Alan have both had more than their share of health scares, but these were always handled with the greatest equanimity—so that it often seemed that they were the ones reassuring their friends, rather than vice versa. Lots of grandmothers I know carry around their grandchildren's pictures, but Alan might be the only man I know who, at the slightest provocation, will show you iPhone photos of his 2 year-old granddaughter, Charlotte, holding her twin baby sisters, Lilly and Emilia. Despite all the demanding roles that Alan has taken on professionally, he has consistently found that balance of life priorities that so often eludes leaders: as a husband, father, grandfather, brother, and friend, he manages to be fully present whenever he is with you.
