Many colleagues, students, and support staff made extensive contributions to the collection, analysis, and interpretation of data from the study. Much credit for the many aspects of the work that went well goes to these contributors; the responsibility for what went awry is, of course, mine. A very special acknowledgment, however, is due Sherry L. Willis, my wife and colleague, who has codirected the Seattle Longitudinal Study efforts since 1982 and without whose patient support and many helpful suggestions this volume would not exist. Recognition is also owed for the enthusiastic support provided by the staff and membership of the Group Health Cooperative of Puget Sound throughout our long period of collaboration.

The Seattle Longitudinal Study has previously been funded by grants from the National Institute of Child Health and Human Development (HD00367, 1963–1965; HD04476, 1970–1973) and by the National Institute on Aging (AG00480, 1973–1979; AG03544, 1982–1986; AG04770, 1984–1989, R037 AG08055, 1989–2004; AG027759, 2006–2008). Current support from the latter institute (R037 AG024102, 2005–2015) is funding the collection of biomarker and MRI data as well as continuing analyses of the cumulative longitudinal data.
