Gergonne Biography of joseph gergonne (17711859) joseph gergonne s father was anarchitect and also a painter. However, he died when joseph was twelve years old http://www-groups.dcs.st-and.ac.uk/~history/Mathematicians/Gergonne.html
Extractions: Version for printing Joseph Gergonne In 1791 the French Assembly was at a difficult stage trying to stabilise the country following the French Revolution. The Assembly was not helped by the King, Louis XVI, attempting to flee the country in June of that year. After the King was returned to Paris, the Assembly reinforced the frontiers of France by calling for 100,000 volunteers from the National Guard. Gergonne gave his support becoming a captain in the National Guard. In April 1792 France went to war against Austria and Prussia. The French attack was quickly halted and then Prussian forces invaded France. The Assembly called for 100,000 military volunteers and Gergonne joined the French army being assembled to defend Paris against the Prussians. On 20 September 1792 Kellermann led the French forces at Valmy with Gergonne in his army. The French defeated the Prussians in an artillery duel and, following this, the Austrian and Prussian armies retreated from France. Following this great French victory, Gergonne went to Paris where he became a secretary to his uncle. It was a time of much military action, however, and Austria and Prussia were not going to simply accept the defeat at Valmy as the end of the war. By 1793 they were joined by Spain, Piedmont, and Britain. The French forces were soon in trouble, fighting on many different fronts and being defeated everywhere. Gergonne returned to the French army, this time as secretary to the general staff of the Moselle army.

Isogons center called the gergonne point, named for joseph gergonne (17711859). This means the Lemoine Point of the gergonne Triangle is the gergonne Point http://www.pballew.net/isogon.html
Extractions: Isogonic is a related word that describes a type of symmetry between lines, passing through the vertex of an angle, and the angle bisector. In the figure Angle ABC is shown with its bisector BB'. The rays BX and BY are isogonal because they make the same angle with the angle Bisector. We often say that one is the isogonal reflection of the other, but it should be clear that if L2 is the isogonic reflection of L1, then L1 is the isogonic reflection for L2. Two points on these rays, such as X and Y, are called isogonal points. If three lines in a triangle are concurrent , then their isogonic lines are also concurrent. In the figure the Red segments AA', BB', and CC' intersect at Point X. The three blue rays are the isogonic lines for the three Red Segments, which are reflected about the angle bisectors (dashed rays). Blue Rays intersect in a single point also, labled X'. Points X and X' are called isogonal conjugates One famous pair of isogonal conjugates is the orthocenter (intersection of the altitudes) and the circumcenter (center of the circle which circumscribes a triangle). If you draw any triangle and find these two points (lets call them P and Q), then draw the angle bisector from any vertex of the triangle (which we will call AX, you will see that the angles PAX and QAX are congruent.
