AT the annual dinner of the Institute of Fuel held on November 12, H.R.H. the Duke of Kent presented the Melchett Medal to Dr. Friedrich Bergius, the distinguished German chemist and pioneer in the manufacture of oil from coal. In Germany, Dr. Bergius's hydrogenation process has for several years been used for the production of petrol from brown coal. Methods based on Dr. Bergius's discovery are now being developed in the United States and in Great Britain. At present, Dr. Bergius is working on the production of sugar from wood.
