 BRIAN G. MARSDEN (1937-2010)
      It is with deep regret that we must announce the death today
 of Brian G. Marsden after a lengthy illness.  He will be remembered
 as contributing much to celestial mechanics and the dynamics and
 orbits of minor bodies of the solar system and as having an encyclopedic
 knowledge of the history of astronomy.  He was a dedicated servant to
 the astronomical community for many decades, serving as Director of the
 Central Bureau from 1968 to 2000 (and as Director Emeritus since then)
 and as Director of the Minor Planet Center from 1978 to 2006 (and as
 Director Emeritus since then).  He also served extensively within
 Commissions 6 and 20 of the IAU over the years, being past President of
 both Commissions.  And he was one of the most visible astronomers in
 the world over the years in terms of his generous availability to the
 news media on behalf of the astronomical community.
