An overview of the development of cosmology over the last 100 years from the Big Bang models of the Universe to the astounding revelation of recent years in that we have no real understanding of 96% of its content! Or even that our Universe could just be one small part of a Multiverse that extends beyond our imagination! Professor Ian Morison began his love of astronomy when, at the age of 12, he made a telescope out of lenses given to him by his optician. He attended Chichester High School and then went on to study Physics, Mathematics and Astronomy at Hertford College, Oxford. In September 1965, he became a research student at the University of Manchester's Jodrell Bank Observatory. In 1970 he was appointed to the staff of the Observatory and teaches astronomy at the University of Manchester. In 1990 he helped found the Macclesfield Astronomy Society which meets at the Observatory and later became president of the Society for Popular Astronomy, the UK's largest astronomical society. He remains on the Society's Council and holds the post of instrument advisor helping members with their choice and use of Telescopes. He lectures widely on astronomy, has co-authored books for amateur astronomers and writes regularly for the UK astronomy magazines Astronomy Now and Sky at Night. He also writes a monthly sky guide for the Observatory's web site and produces an audio version as part of the Jodrell Bank Podcast. He has contributed to many television programs and is a regular astronomy commentator on local and national radio. Another activity he greatly enjoys is to take amateur astronomers on observing trips such as those to Lapland to see the Aurora Borealis and, last year, to Turkey to observe a total eclipse of the Sun. In 2003 the Minor Planets Committee of the International Astronomical Union named asteroid 15,727 in his honor citing his work with MERLIN, the world's largest linked array of radio telescopes, and that in searching for intelligent life beyond our Solar System in Project Phoenix. Ian is excited about the prospect of his time as Gresham Professor of Astronomy. He regards it as real challenge and expects it to play a major role in his life for the next three years. He will to give a wide variety of illustrated lectures ranging from how our understanding of the Universe has grown over the centuries to a gentle introduction to Einstein's theory of Gravity - now being tested to extreme accuracy by astronomers at Jodrell Bank. He realized that his love of observational astronomy could not easily be covered in the City of London, so has instituted a Gresham Astronomy Weekend at a 'dark sky' location in the Cotswolds which will take place in March each year.
