--Luca Pacioli--Luca Pacioli

Leonard of Pisa (1170-1250), better known as Fibonacci, introduced the Fibonacci Series, a sequence of numbers; 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, … in which any number is the sum of the two preceding members.

0 + 1 = 11 + 1 = 21 + 2 = 32 + 3 = 53 + 5 = 85 + 8 = 13 etc.
