History of diabetes of 1923, 25,000 patients were being treated in Canada and the United States. For this, Banting and laboratory director John MacLeod received the Nobel Prize in Physiology or Medicine in 1923; both shared their Prize money with others in the team who were not recognized, in particular Best and Collip.

The distinction
Highest and best use a series of tests. The exact definition of highest and best use varies, but generally the use must be the following: Only those uses that are, or may be, legally permitted are potential highest and best uses. This may exclude uses that are not, and unlikely to become, permitted by zoning, land use planning, uses forbidden by government regulations, and uses prohibited by deed restrictions or covenants. Properties with a use that predates existing zoning or other property regulations may be "legally nonconforming". Such "grandfathered uses" are generally legal even though they do not meet current zoning or other regulations.
