The Brocard point of a triangle is the point 
in triangle 
such that 
. It is also the unique point inside such that the sum of the distances from to 
and 
is a minimum. These points are named after Henri Brocard (1845 – 1922), a French mathematician. https://en.wikipedia.org/wiki/Brocard_points and here: http://mathworld.wolfram.com/BrocardPoints.html.
