The Resume

    (1170-1250)
    Birth name was Leonardo Pisano
    Wrote Liber Abaci (1202), Practica Geometriae (1220), Flos (1225) and Liber Quadratorum

Why he might be annoying:

    He was also known as Leonardo Bigollo and Leonardo da Pisa.
    His work was somewhat ignored for three centuries.
    Because his father was a wealthy merchant/diplomat, he was able to travel and not concentrate on earning a living.
    Since his writings were before the printing press, all copied had to be hand written and thus some of his writings are lost, including a commentary on Euclid.
    When he wrote a second edition of Liber Abaci he prefaced it with 'new material has been added [to the book] from which superfluous had been removed' (1928).

Why he might not be annoying:

    He widely introduced Europe to used the Arabic numeral system rather than Roman numbers.
    His famous Fibonacci sequence is that each number is equal to the sum of the previous two numbers (1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, etc)
    He studied math in Italy and in North Africa and thus had a working knowledge of arabic and hindu mathematics.
    His father desired that he study accounting and that is how he became interest in the art of math.
    All of his books were hand written.
    He met with Emperor Frederick II (1225).
    Many of his math problems are still used as brainteasers today.
    He discovered that all square numbers ascend from a regular sequence of odd numbers.
    He defined the congruum.
    He explained the importance of zero.
