The latest edition of the Biographical Directory of Scientists lists 2623 who are now in Iowa or were formerly here. For every twenty-one of the present North American scientists, two are or were Iowans. Of these Iowans, 1110 were born in Iowa. Only six states have a larger number of native scientists. Of the outstanding or "starred" scientists, fifty-nine are native Iowans, a number exceeded by only five states. There is a native Iowa scientist for every 2275 of Iowa's present population, a ratio exceeded only by two states, each with a much smaller population, namely, Vermont and Utah.
