My grandfather invented the cold air balloon...
It never really took off.
Sir Frederick Gowland HopkinsDied 16 May 1947 at age 85 (born 20 Jun 1861). English biochemist who shared (with Christiaan Eijkman) the 1929 Nobel Prize for Physiology or Medicine for discovery of essential nutrient factors, now known as vitamins, needed in animal diets to maintain health. Hopkins fed young rats on a basic diet which, in addition to the necessary salts, contained a carefully purified mixture of lard, starch, and casein (the most abundant protein in milk). After some time the animals ceased to grow. Then Hopkins demonstrated that it was only necessary to add a very small daily amount of milk, 2 - 3 cc for each animal, for growth to recommence. Thus the sufficiency of food consumed without the added milk could be fully utilized by the body only when the growth-promoting influence of the milk was present. |
