Did commercial deployment of Lucky's adaptive equalizer raise voiceband data rates to 9600 bps (4x the ~2400 ceiling), and is that figure in any primary source?

Were Lucky's (Bell Labs) and Widrow's (Stanford) adaptive-filter groups aware of each other in the mid-1960s, or did they converge independently?

Robert Lucky's 1965 adaptive equalizer broke the telephone-line 'distortion barrier' using the same steepest-descent adaptive-filter logic as Widrow's LMS
