After several decades of patient waiting for the D.U. Club to pass, Delta Upsilon chartered yet another chapter at Harvard. The new chapter was installed in 1999, four years after the D.U. Club had merged with the Fly Club. It unraveled faster than its predecessors, however. In 2005 the six-year-old Delta Upsilon chapter voted to disaffiliate from the fraternity. It has continued under the name "Oak Club" and currently claims more than 100 alumni who, it says, embody "many of the original DU principles".
