at Siding Spring.
Named in honor of David {Anthony} Allen {19461994}, staﬀ astronomer at the Anglo-Australian
Observatory (AAO). Following his Ph.D. from Cambridge University, Allen held research fellowships at
the Hale Observatories and the Royal Greenwich
Observatory. In 1975 he became one of the ”founding
members” of the scientiﬁc staﬀ of the AAO, initially
as a research fellow. He has remained as one of the
pillars of that establishment ever since, having become
the only permanently-appointed research astronomer.
Notable for his extraordinarily wide interests across
all astronomy, from the solar system to observational
cosmology, his main contributions have been in the
ﬁeld of infrared instrumentation and its applications.
He developed the radiometric method for determining
asteroid diameters and recently discovered several new
infrared ”windows” in the atmosphere of Venus. Allen
is also a leading ﬁgure in public education in astronomy,
contributing to many radio and TV programs and the
author of many popular articles and several books.
