Colloquium on the Age of the Universe, Dark Matter, and Structure Formation NATIONAL ACADEMY OF SCIENCES Colloquium Series In 1991, the National Academy of Sciences inaugurated a series of scientific colloquia, five or six of which are scheduled each year under the guidance of the NAS Council’s Committee on Scientific Programs. Each colloquium addresses a scientific topic of broad and topical interest, cutting across two or more of the traditional disciplines. Typically two days long, colloquia are international in scope and bring together leading scientists in the field. Papers from colloquia are published in the Proceedings of the National Academy of Sciences (PNAS).

Colloquium on the Age of the Universe, Dark Matter, and Structure Formation David N.Schramm 1945–1997 David Schramm died in a plane crash while travelling to his beloved home in Aspen, Colorado. He organized this conference and many others. He loved science; his research work was strong and effective. He was a tireless advocate for support of research by younger people, and all who knew him will remember his exuberant enjoyment of life. These colloquium proceedings are devoted to his memory—a valued friend and colleague. —P.J.E.Peebles
