I would like to add my perspectives, although minor, to the list. I was not as directly involved but I remember all the energy on the 3rd floor of the engineering building. After reading all the various commentaries, it all makes a little more sense now.

My first contact with Dr. Culler was in 1970, when I implemented an FFT into the Culler-Fried System. I was doing a project for Dr. Gray who was an intense user of the System. Programming the FFT in 360 assembly language was a little disorienting as well as only getting to try out the software at wierd hours in North Hall when nobody was using the system. Anyway, Dr. Culler appreciated the addition of the FFT and wanted to add digital filtering capabilities. I ended up adding the digital filtering onto the SEL810 Speech System on the 3rd floor of the engineering building (the SEL810B Speech System was originally built by Dave Retz, but I got all my systems advice from John McAfee). Later on I worked with Dave Retz at SCRL.

As a student in Dr. Culler's class on digital filtering, at CHI on Aero Camino Road, I marveled at his enthusiasm as we explored basis functions relating the postion of impulses in the frequency domain to the frequency of sinusoids in the time domain. (Looking back, I can't find "basis functions" in my books but I'm sure that's what they were called. At least that's what stuck in my head.)

As an occasional visitor at CHI on Aero Camino to see Jim McGill or Jan Vanderford, I was always amazed at the excitement in the air, e.g. array processors, speech modeling, ARPA net connections, etc.

I hope this perspective helps in filling in the picture of Dr. Culler's contributions to the computer industry.
