The earliest published work on the "precedence" effect in acoustics was 
by Joseph Henry c.a. 1850 (THAT Joseph Henry, whose name is on the unit 
of inductance).  It's the basis of the Bell Labs patent for stereo c.a. 
1936, a method far superior to the one published in the UK in the same 
time frame. Henry was heavy duty in science in those days -- he 
consulted on the acoustic design of the meeting rooms of the houses of 
congress, and on acoustic propagation of sound from foghorns. He was 
first director of the Smithsonian; the government closed for the day he 
died and the day of his funeral! We could use that sort of respect for 
science today. :)

Precedence effect is now most commonly called the "Haas Effect" as the 
result of a graduate-level paper published by Helmutt Haas nearly a 
century after Henry.
