The Ann and Robert H. Lurie Tower, located on North Campus at the University of Michigan in Ann Arbor and housing a grand carillon -- one of only 23 in the world, but one of two on the Michigan campus -- was built in 1996 as a memorial for Michigan alumnus Robert H. Lurie. The Lurie Tower was designed by Michigan alumnus Charles Moore (AB '47, Hon Arch Ph.D. '92) and was dedicated in October 1996. A gift of the "Ann and Robert H. Lurie Family Foundation," it has 60 bells. Ann Lurie of Chicago donated $12 million in memory of her husband, Robert H. Lurie (BSE '64, MSE '66), to help fund the construction of North Campus buildings, including a bell tower. Completed in late 1995, the 167-foot (50.9 m) tall bell tower is a significant landmark on the evolving North Campus. The bells of this grand carillon, which is lighter in weight than the Burton Tower's 55-bell carillon, are cast in bronze, in the customary proportion of 80 percent copper to 20 percent tin, at the Royal Eijsbouts bell foundry in Asten, Netherlands. The North Campus bourdon bell weighs in at six tons.
