In 1960, the British scientist/novelist C P Snow gave a lecture–later turned into a book–which was inspired by the following thought:
One of the most bizarre features of any advanced industrial society in our time is that the cardinal choices have to be made by a handful of men: in secret: and, at least in legal form, by men who cannot have a first-hand knowledge of what those choices depend upon or what their results may be…and when I say the “cardinal choices,” I mean those that determine in the crudest sense whether we live or die.
Snow discusses two very cardinal cases in which he was personally if somewhat peripherally involved: the pre-WWII secret debate about air defense technologies, and the mid-war debate about strategic bombing policies. This post will focus on the first of these debates, the outcome of which quite likely determined the fate of Britain and of Europe. (Snow’s version of these events is not universally accepted, as I’ll discuss later.) Follow-on posts will discuss the strategic bombing debate and the issues of expertise, secrecy, and decision-making in our own time.
The air defense debate had two main protagonists: Sir Henry Tizard, and Frederick Lindmann (later Lord Cherwell.) These men were similar in many ways: both were scientists, both were patriots, both were men of great courage (involved in early and dangerous aircraft experimentation), both were serious amateur athletes. They were “close but not intimate friends” when they both lived in Berlin–Tizard was a member of a gym there which was run by a former champion lightweight boxer of England, and persuaded Lindemann to join and box with him. But Lindemann proved to be such a poor loser that Tizard refused to box with him again. “Still,” says Tizard, “we remained close friends for over twenty-five years, but after 1936 he became a bitter enemy.”
Snow, who makes no secret of his preference for Tizard, tells of a conversation with Lindemann in which he (Snow) remarked that “the English honours system must cause far more pain than pleasure: that every January and June the pleasure to those who got awards was nothing like so great as the pain of those who did not. Miraculously Lindemann’s sombre, heavy face lit up…With a gleeful sneer he said: ‘Of course it is. It wouldn’t be any use getting an ward if one didn’t think of all the people who were miserable because they hadn’t managed it.'”
Some people did like Lindemann, though–and one of them was Winston Churchill, who though still in the political wilderness was not without influence. Indeed, the future PM considered Lindemann (later to become Lord Cherwell) to be his most trusted advisor on matters of science. If Snow’s version of events is correct, Churchill’s trust and advocacy of Lindemann could have driven a decision resulting in Britain’s losing the war before it even started.
During the inter-war era, the bombing plane was greatly feared–it was commonly believed that no effective defense was possible. PM Stanley Baldwin, speaking in 1932, expressed this attitude when he said “I think it is well also for the man in the street to realize that there is no power on earth that can protect him from being bombed, whatever people may tell him. The bomber will always get through.” Indeed, the problem of air defense was very difficult–the bombers could arrive at any time, and by the time they were sighted, it would likely be too late to get fighters in the air. Maintaining standing patrols on all possible attack routes was unfeasible. The only detection devices were long horns with microphones and amplifiers, intended to pick up enemy engine noise a considerable distance away–but their value was limited to say the least.
In early 1935, the British government set up a Committee for the Scientific Study of Air Defense, chaired by Tizard. It reported to a higher-level committee, chaired by Lord Swinton, who was the Air Minister. One member of that higher-level committee was Winston Churchill, and he insisted that his favorite scientist, Lindemann (who had been quite vocal about the need for improved air defense), should be appointed to Tizard’s working-level committee.
Radar had only recently been invented, and was by no means operationally proven, but all of the members of that Tizard committee–with one exception–viewed it as the key to successful air defense. That exeption was Lindemann. While not hostile to radar, he believed the committee should given equal or greater attention to certain other technologies–specifically, infrared detection and parachute mines…the latter devices were to be dropped from above, and were intended to explode after getting caught on the wing or other part of the enemy bomber. He also thought there were possibilities in machines that would create a strong updraft and flip a bomber on its back.
“Almost from the moment that Lindemann took his seat undisturbed in the committee room,” says Snow, “the meetings did not know half an hour’s harmony or work undisturbed.” Exercising his novelistic talents, Snow imagines what the meetings must have been like:
Lindemann, Hill, and Blackett were all very tall men of distinguished physical presence…Blackett and Hill would be dressed casually, like academics. Tizard and Lindemann, who were both conventional in such things, would be wearing black coats and striped trousers, and both would come to the meetings in bowler hates. At the table Blackett and Hill, neither of them specially patient men nor overfond of listening to nonsense, sat with incredulity through diatribes by Lindemann, scornfull, contemptuous, barely audible, directed against any decision that Tizard had made, was making, or ever would make. Tizard sat it out for some time. He could be irritable, but he had great resources of temperament, and he knew that this was too serious a time to let the irritability flash. He also knew, from the first speech that Lindemann made in committee, that the friendship of years was smashed.
