<p>If we take membership in the Association of American Universities as a indicator of the most prestigious research universities, one might consider membership as the ultimate peer assessment. It is interesting to look at when particular universities were invited to join the club. Listed below is a list of the members according to date of membership. If we take the founding members as the top research universities of 100 years ago, we find that they are still in the top rankings today. Others that joined AAU in its early years clearly have slipped according to today’s rankings. It is notable that the rise of others is only relatively recent, even though they are considered near the top of today’s rankings; earlier in the last century they didn’t rate. It’s also interesting to look at the number of years between the membership of different universities: Missouri got into the club in 1908, but it was 30 more years before Duke was considered good enough. Since then Duke has risen, but Missouri has fallen by today’s rankings. After Stony Brook and Texas A&M joined in 2001, it was 9 more years before another university(Georgia Tech) was invited to join.</p>
