Session 1 - HAD I: LeRoy E. Doggett Memorial Session.
Oral session, Tuesday, January 06
During the period of 1975 to 1996 The Nautical Almanac Office (NAO) underwent a number of changes in the publications and products of the office. There was also an organizational change in 1990, when the NAO name changed from being a department to a division within the Astronomical Applications Department. LeRoy E. Doggett was responsible for editing and publishing during the period. The Air Almanac was reduced from three to two volumes per year in 1977 and from two to one in 1987. In 1977 the Almanac for Computers was introduced. In 1981 a reformated and single publication,"The Astronomical Almanac", replaced "The Astronomical Ephemeris" published in the U.K. and "The American Ephemeris and Nautical Almanac' published in the U.S. The bases for the publication were changed in 1984. The Floppy Almanac was introduced in 1986 and MICA was introduced in 1993. In addition to the publications LeRoy Doggett handled phone calls and letters, particularly about phenomena, calendars, and history. This was done in both a scholarly and user friendly style.
