The Rho Chapter of Delta Tau Delta fraternity will mark its 135th anniversary with a big birthday bash and reunion on campus. The celebration will be held on April 24, 2010, with a tent from 2 to 5 p.m. and a barbecue near DeBaun Field, where Stevens men’s lacrosse will battle Nazareth College at 3 p.m. Tours of the Delt house on Castle Point Terrace will also be held during the afternoon. That evening, Delts and their guests will mingle for cocktails and hors d’oeuvres inside the Babbio Center atrium, starting at 8 p.m. “It’s important to get together and have a good time,” said Bruce Boylan ’63, who is organizing the event. “We’re also going to be honoring a few people, but that’s top secret.” The cost is $50 for individuals and $75 for couples, with proceeds benefiting the Delta Tau Delta Rho Chapter Scholarship. The Delt celebration coincides with Stevens’ Spring Sports Day, which includes the barbecue, other events and fireworks over the Hudson River at 10:45 p.m. Visit stevens.ducks.com/springsports day.asp for information. The Rho Chapter turned 135 in 2009, as the fraternity was founded at Stevens on May 9, 1874. The chapter held its first anniversary celebration in 2000, when it turned 125.
