I hate having to correct my own email responses, but I missed an 
important detail in the original post: It refers to the first transistor 
"IC." So the correction indicating 1959 is right. I recall a side trip 
tour of Bell Labs at Murray Hill in early 1961 when I was trying to 
decide where to go for an EE degree program. One of the  labs we toured 
was involved in perfecting integrated circuit design and fabrication 
techniques, and we were told that they had been working on this project 
for few years. The primary goal of that particular project was to 
improve the high frequency performance of the devices.
