As an opposite, Table 7 presents the top most unprolific authors, who have just published 2 papers (from 1960) and yet in the top 2% list. A curious case is Irving Langmuir who first published in 1906 and last in 1997 (91 years) with only 2 papers but ranked #612. Irving Langmuir was an American chemist and physicist, who was awarded the Nobel Prize in Chemistry in 1932 for his work in surface chemistry. Another great example is G.H. Hardy who published from 1901 to 2003, yet only has 2 papers. Several bizarre entries again show some dubious and defective entries in the database.
