This is for my buddy Tom Brown who thinks that my claim that Macro was born with Keynes's GT was very bold
"As to your assertion that no macro existed before Keynes, that strikes me as a bold statement!! I'm going to look a few things up right now in real time: my first thought is all the stuff I've ever read at Glasner's: about Hawtrey and others that preceded Keynes... and even going WAY back to John Stuart Mill, Say and Marx... OK, let's see what Wikipedia has to say:
http://en.wikipedia.org/wiki/History_of_macroeconomic_thought
"OK, I think you're wrong ... but you're not as wrong as I thought:
"Modern macroeconomics can be said to have begun with Keynes and the publication of his book The General Theory of Employment, Interest and Money in 1936"
"I didn't know that! I knew that book was very influential, but I've never heard that before. Interesting."
. From the first page of Richard Koo's preface to The Holy Grail of Macroeconomics is this quote of Bernanke:
"Not only did the Depression give birth to macroeconomics as a distinct filed but the experience of the 1930s continues to influence macroeconomists beliefs, policy recommendations, and research agendas.

Ok, I'll admit that it sounds 'bold' when you talk to people like Sumner, or even Nick Rowe and David Glasner as they are Monetarists who don't want to admit that Keynes invented Macro-though Freidman himself sort of admitted it. Even Bernanke doesn't mention Keynes but the timing is obvious. This is because Monetarism is really a Trojan Horse for Keynesianism. It tried to beat it by joining it-sort of. It acknowledges AD and the business cycle but it still tries to keep the world safe for laissez-faire.
There's been a good deal of debate lately about what Keynesianism means and what Say's Law was. However, I think much of it just confuses the matter. Keynesianism means the need of fiscal policy to get us through demand slumps. Monetarism's promise to conservatives is that it will deliver everything they want by kind of accepting the birth of Macro and sort of being part of it. Yet while other conservative schools-Austrianism, RBC, Supply Siders-don't acknowledge Macro at all-they still insist that Micro is enough-while Monetarism accepts the birth of Macro along with Keynesians, they are on the side of the other conservative schools and seek to 'crush the infamous thing'-as Sumner shows on a daily basis.
P.S. Tom does go on to say this after reading Wiki.
"Mike, I took them at their word: "Modern" macro started with Keynes, but it seems there was some fooling around before that time in trying to explain the business cycle, etc. My history on the subject isn't good, maybe for all practical purposes you are right. If you define it in terms of when the concept of aggregate demand appeared, etc."
"Still, that's interesting to me: I didn't know that Keynes was the first to come up with the concept of aggregate demand. Very interesting"

It's important not to mix up a few things. Keynes didn't invent the idea of the business cycle that was kicking around at the time though was very new. Previous to this economics believed in Say's Law that 'Supply creates its own demand' or that there can be no general glut. This meant that there could be an invidiual market that failed to clear but not in all markets.
Some of these ideas of Keynes were already fermenting in the Cambridge School-from folks like Pigou, et. al-but they actually hatched with Keynes. The idea of a 'general glut' was argued before Keynes-perhaps going back to Maltus' debates with Ricardo. However, Keynes gave ideas like this a real theoretical foundation for the first time. However, the real difference is that with Keynes, methodological individualism is now checked-you can't know the economy simply by examining individuals in isolation.
