Who is your Favorite Historical Conductor?

For discussion purposes I am limiting this to

1) Wilhelm Furtwangler

2) Arturo Toscanini 

3) Bruno Walter

feel free to introduce others.  I will be arbitrary and cut off Conductors who worked after the death of Leonard Bernstein.

  Furtwangler and Toscanini died just short of the onset of the stereo era.  They were however recorded with the best technology of the times, and the work of restoration technology of today has done wonders.  Walter recorded until 1962 but perhaps his best work was done in the mono era.

  Walter was renowned for his “humanity” Furtwangler for his near mystical ability to rechannel German/Austrian music, and Toscanini for his finely chiseled intensity
