|Gb, Symbols: Gi a unit of magnetomotive force; the magnetomotive force resulting from the passage of 4π abamperes through one turn of a coil. 1 gilbert is equivalent to 10/4π = 0.795 775 ampere-turn|

American biologist. He shared a 1980 Nobel Prize for developing methods of mapping the structure and function of DNA.
|Gilbert (gĭl'bərt) Pronunciation Key
American biologist who, building upon the work of Frederick Sanger, formulated a method for determining the sequence of bases in DNA that made it possible to manufacture genetic materials in the laboratory. For this work he shared with Sanger and American biologist Paul Berg the 1980 Nobel Prize for chemistry.
|Gilbert, William 1544-1603.
English court physician and physicist whose book De Magnete (1600) was the first comprehensive scientific work published in England. Gilbert demonstrated that the Earth itself is a magnet, with lines of force running between the North and South Poles. He theorized that magnetism and electricity were two types of a single force and was the first to use the words electricity and magnetic pole.
