     Georges-Louis is more commonly known as Comte de Buffon.  He grew up in a family of five in the region of Dijon, France.  Since his father was the Lord of Dijon and Montbard, he was raised in a    high-class society.  At the age of ten, he began attending Jesuit College, pursuing studies in mathematics.  Soon he changed his mind and concentrated on 
law.  Before starting his new position practicing law, Buffon decided to follow his interests in medicine and botany. 

     In 1723, a year after his mother’s death, he pursued many interests due to the flexibility his inheritance gave him.  He dabbled in mathematics, physics, botany, and chemistry.  During this time period, he wrote numerous papers, conducted a study of probability, and a study of the physics of Isaac Newton.  During the later years of his life, Buffon concentrated on his scientific interests.  For 48 years, he dedicated his time and energy compiling a comprehensive history of all the natural sciences.  This tremendous achievement was a forty-four volume work entitled Historie naturelle, générale et particulière.  Buffon died at the age of 81 in Paris, France (Magil, 1989).

     Buffon created an example of geometrical probability in 1777, which interested many people.  This may explain the use of this problem in classrooms today, as well.  This method of calculation is called Buffon’s Needle.   This method allows individuals to approximate the numerical value of by throwing a needle.  The needle lands on a plane containing parallel and equidistant lines.  To determine the numerical value of , one would count the number of times the needle hits a line (Struik, 1967).
