I will miss Dave: -his no nonsense approach and ability to voice what others were thinking but unwilling to say -his persistent desire to get the right outcome even when out numbered -his enthusiasm for science, technology and pushing the boundaries -his pride and love for his family which shone through given half a chance in the busyness -his positive impact in developing and encouraging colleagues with his pithy sayings and anecdotes -his willingness not to take things too seriously (including himself)
