Jerry Bayless - A∆1065

Jerry came to Rolla in 1955 to study engineering at what was then known as the Missouri School of Mines and Metallurgy. After earning his bachelor’s degree in civil engineering in 1959, he joined the civil engineering faculty while pursuing a master’s degree in that discipline. He remained on the faculty and held various administrative positions until his retirement 58 years later in February 2017 along with serving as academic advisor for our chapter. Known by students and alumni as “Mr. MSM,” “Mr. UMR” or “Mr. S&T,” depending on the era, or simply as “Mr. Miner” to many, he is also remembered as a dedicated professor who was the “heart and soul” of Missouri S&T. He served as an assistant chair of engineering, assistant dean of engineering, associate dean, and in 2004, the university presented him with the Chancellor Medal in recognition of his service.

The Faenger Brothers - Bob A∆519, Gene A∆580, and Al A∆609

Upon Bob’s initiation, his younger brother, Gene Faenger ’65, got to know many Alpha Delta Zeta members before he came to Rolla to start school. Fortunately, the decision to join ΛXA was hardly a challenge for Gene. “Everyone was great,” Gene said. “There was no other choice for me.” When their younger brother, Al Faenger ’68, pledged in 1961, it truly became a family affair. “I never gave it a second thought not to pledge,” Al said. Throughout each of the brother’s time in the Chapter, they served in several leadership positions both in the Fraternity and around the Missouri S&T campus. “Lambda Chi Alpha provides brothers with people and administration skills for life,” Gene said. “All of us are examples of that.”


Leonard Kirberg A∆610

He was a civil engineer and innovative industry leader as a chairman, CEO, and president of Horner & Shifrin Inc. from 1988 to 2004. Len received his bachelor of science in civil engineering from the University of Missouri-Rolla in 1966. Under Len’s guidance, the Housing Corporation undertook their much-needed capital campaign for a new Chapter House at 1705 Pine St. Brothers shared his ambitious goal of completing the project before the Chapter’s centennial celebration in November of 2017. His goal was met, as the capital campaign raised more than $2 million. Because of Len’s vision, leadership, and perseverance, the men of Lambda Chi Alpha will enjoy one of the best homes on Missouri S&T’s campus for years to come.


Dr. Harry B. Smith - A∆226

Raised in the greater Baltimore, MD area, Harry graduated from Rolla with a degree in Electrical Engineering in 1942. Serving the United States Army in the elite intelligence unit at Harvard and MIT, Harry led a group of engineers developing electronic systems to analyze code. This work was part of the famed “Enigma Project” that helped the Allies break German code.  At the end of WWII, Harry and two other Westinghouse Air Arms Division engineers created and developed pulse-Doppler radar, which allowed high altitude surveillance aircraft to detect and track moving targets despite obstructions of sight such as clouds or trees. He is known as the “Father of pulse-Doppler radar.”
