Ivars Peterson (MathTrek)  
Once someone discovers an interesting pattern or type of behavior, those particular numbers are likely to earn a collective name. So we have perfect numbers, amicable numbers, lucky numbers, Mersenne numbers, Fermat numbers, Fibonacci numbers, Keith numbers, Niven numbers, Carmichael numbers, Stirling numbers, Catalan numbers, RuthAaron numbers, Rhonda numbers, and so on... One such curiosity came about in 1982 as the result of a telephone call... the birth of Smith numbers, named for the mathematician mathematician Albert Wilansky's brotherinlaw.
