Perhaps the department's greatest legacy, however, lies in its graduates.
"So much of British industry, commerce and finance has been not only influenced but led by so many graduates from this department," Coyne told the audience. "Some incredibly modest yet distinguished individuals in this audience today have played a huge part in that."
Among those in attendance were Kevin Ellis, former Chairman of PwC UK; Michael Queen, former CEO of 3i; Andy Halford, former CFO of Vodafone and Standard Chartered; and Errol Gardner, current Global Vice Chair of Consulting at EY.
Gardner, who studied Industrial Economics between 1987 and 1990, reflected on returning to campus, and how the value of the degree has only grown throughout his career.
"It's always a delight to be back," he said. "Part of the reason I came to this university was the beauty of University Park. It's been great to hear the stories of people who've gone on to do many different things."
"You never quite appreciate, when you do a degree like Industrial Economics, the skills that it teaches you," he added. "With every new experience, it becomes more relevant to the way you think about and approach your work."
For Gardner, the course's blend of economics, business and practical application provided a foundation that remained valuable decades later as he moved from accountancy into consulting and leadership.
The celebration also looked firmly to the future. Current students and recent graduates connected with senior alumni throughout the afternoon, offering a reminder that the department's story continues to be written.
For final year undergraduate Daniel Damasceno de Faria, the enduring appeal of Industrial Economics lies in its practical relevance.
