Roger's creative use of fluorescent protiens is a significant foundation of modern molecular biology. A huge number of therapies, technologies and underatanding of biology come not just from our ability to 'see' the biological tools themselves, but from the idea that a novel biological tool can be made from conferring the properties of one protien with the properies of another. Unfortunate to lose him.
