Dr Michael Creeth: Scientist who helped pave the way for Watson and

Michael Creeth had a long and distinguished scientific career and made a significant contribution to one of the greatest scientific discoveries of the last century, when as a young PhD student his experiments confirmed the existence of the special bonds known as hydrogen bonds which hold the two strands of the DNA molecule together. This finding, based on measurements of the viscosity of highly purified solutions of DNA, was published in 1947 and proved crucial for the Nobel Prize-winning discovery of the double helix six years later by James Watson and Francis Crick.
