An old, rare IBM film about SAGE recently surfaced on YouTube -- what a fantastic resource that web site is. The film brought back many discussions I've had with my colleagues about the place of SAGE in the history of computing. Paul Edwards saw SAGE as the centerpiece of the "Closed World" of computing. IBM historians have discussed its role...

Despite my dissertation research on Konrad Zuse, I've been accused of a bias toward the American side of computer history. Here are a couple of news items from the U.K. that may offset that. The first concerns what may be the first recording of music generated by a computer--the Manchester "Baby," in 1951! That is 6 years before the famous...

In an earlier post (March 20), I discussed Moore’s Law and its relation to the history of computing. Once again I feel compelled to return to the topic—this time, to discuss its impact, not on computer science and technology, but on its historians. Put simply, historians of technology, including me, find Moore’s Law unnerving. The existence of an exponential growth...

In an earlier post I mentioned the American Computer Museum of Bozeman, Montana. You can look at its web site for details. Now that the weather is getting warm, it is time for all of us who are interested in computing history to figure out a way to get to Bozeman and see it. You don't really need an excuse...

Last February I had the privilege of attending a conference on “ Imagining Outer Space,” held in Bielefeld, Germany. I have been to many conferences on the history of rocketry and space travel, and on the social and cultural implications of the Space Age, but none of them were as stimulating as this conference was. A theme present in almost...

An obituary in a recent Washington Post brought back a flood of memories for me, and reminded me of a topic I had been meaning to discuss but had put aside. Samuel S. Snyder is a name that should be familiar to many historians of computing—he authored an article on “Computer Advances Pioneered by the Cryptologic Organizations” for one of...

Those words were spoken by the late Professor W. David Lewis, of Auburn University, discussing a talk I had given about the relationship of computing to aerospace. We all know the corollary: if you discover a universal solvent, in what container can you hold itFor myself, working at the National Air and Space Museum, this paradox came home forcefully when...

Moore’s Law is an empirical observation—that the density of computer memory chips doubles about every 18 months, and it has been doing so for the past four decades. Magnetic storage capacity, and to a less-regular extent, processor speeds and telecommunications bandwidth have also been increasing exponentially in a complementary fashion. We all know the results, not just in consumer products...

Within the past decade, the cell phone has spread around the world. The iPod is a permanent appendage to teen-agers, while the Blackberry plays the same role for "grown-ups." All these, of course, are based on the microprocessor, whose architecture in turn is based on computer designs that go back at least to the 1960s. The almost universal adoption of...

At first I assumed that everyone out there knows who I am, but perhaps I had better introduce myself. I am Paul Ceruzzi, Curator of Aerospace Computing and Electronics at the Smithsonian's National Air and Space Museum , in Washington, D.C. My interests in the history of computing go back to my graduate school days at the University of Kansas,...
