High Five: 1995 DAC Winners The 1995 recipients of Iowa State University's premier alumni award -- the Distinguished Achievement Citation -- have nothing and everything in common. One plants corn. One forecasts markets. One coordinated military actions. One analyzed food content. One brings dinosaurs to life on the big screen. Helen E. Clark, M.S. '45, Ph.D. '50; Arnel R. Hallauer, M.S. '58, Ph.D. '60; Robert J. Hermann, '54, M.S.'59, Ph.D. '63; D. Gale Johnson, '38, Ph.D. '45; and Edward R. McCracken, '66, form a seemingly disparate band of ISU alumni. But a closer look at their careers through the accompanying stories unearths in each the singular ability to advance their discipline and serve the world. _____ contact: Internal Communications, (515) 294-3129 updated: 5-25-95
