Celebrating 25 Years of Constructor University

Our 25th year anniversary is a year-long celebration of what makes CU great, and an opportunity to highlight the impact Constructors have had on global discourse, research and our connection to the local community. By marking this incredible milestone, we aim to deepen our ties to our alumni, connect with the broader global academic community, foster self-identity with faculty and inspire the next generation of changemakers.

Long before it became a university, this campus was a witness to history, shaped by conflict and recovery, uncertainty and hope – each phase a reminder that places, like people, can be reimagined. The decision to build a university here was not made in isolation; it was the culmination of decades of transformation.

Chancellor Turgut Tülü
25th Anniversary Message
To truly understand where we are going, we must first understand how far we’ve come

To do this, we are highlighting the past 25 years of decision making at Constructor University: by those who have come before us, those who are shaping the future of academia and those who will lead the charge into a new tomorrow. In 2026, we are celebrating the past 25 years of decisions made by faculty, students and visionaries alike to put CU on the global academic map.

A Place of War: Anti-Aircraft Barracks of the Reichswehr (1936-1945)
A Place of War: Anti-Aircraft Barracks of the Wehrmacht (1936-1945)
Our campus grounds were originally conceived and constructed as an army barracks by the Nazis beginning as early as 1936. The military purpose was to build up aerial capacities in Northern Germany, which back then could only have one pragmatic background: going to war with the world.
A Hub of New Beginnings: Displaced Persons Camp (1948-1952)
A Hub of New Beginnings: Displaced Persons Camp (1948-1952)
After the war, Flakkaserne Grohn was first used as the military headquarters of the Bremen enclave, but was converted into a displaced persons camp organized by the IRO (International Refugee Organization) and administered by US Army forces. Over a million forced laborers, liberated concentration camp prisoners and German emigrants were processed on their way to Bremerhaven, leaving Europe to begin life anew.
Suburban Mediocrity meets WWIII: Bundeswehr Army Barracks for the Cold War (1955-1999)
Suburban Mediocrity meets WWIII: Bundeswehr Army Barracks for the Cold War (1955-1999)
During the Cold War, the campus returned to its militaristic roots, this time for the newly established Bundeswehr. Despite the constant fear of the atomic bomb, the site experienced a time of provinciality and calm, which was only interrupted by demonstrations of the peace movement in the 1980s. After the collapse of communism, relocation of the supply unit to the nearby Garlstedt barracks brought an end to the military presence in Grohn.
A University is Born: IUB (2001-2006)
A University is Born: IUB (2001-2006)
With the end of the Cold War came new beginnings. After protracted discussions, a decision was finally made to establish the International University Bremen. It would be the first private full university (Volluniversität) in Germany — a bold transformation, not only of the place itself, but also a massive innovation in Germany's system of higher education.
Gaining International Renown: Jacobs University (2007-2022)
Gaining International Renown: Jacobs University (2007-2022)
The university established itself as an internationally renowned institution with excellent research and innovative approaches in higher education. However, the university continued to face funding challenges. Thanks to a generous contribution by the Jacobs Foundation, the university, thereafter renamed Jacobs University Bremen, was kept afloat. The public-private model soon came to an end, as both the Jacobs Foundation and the Freie Hansestadt Bremen declined to fund the university further.

Constructing the Future: CU (since 2022)
After a prolonged search for an investor, Constructor University was born. The shift to Constructor University also marked the end of any financial support through the public sector. The newly founded university set its sights on becoming an innovative institution on the cutting edge of scientific and educational development, focused on rapid growth and self-sustained financial stability.
Legacy & Leadership: 25 Years of Constructing the Future

The decisions made by founders who imagined a new kind of university in Bremen – one built on global collaboration and advancing knowledge and technology to make learning more effective for all. The researchers who pursued the questions others overlooked, empowering the next generation of scientists, professionals, and leaders. The students who crossed borders to shape their futures. And the Constructors whose early work laid the foundations of research and innovation that continue to define our community today.

As a guest lecturer in May 2025 for the “Entrepreneurship & Innovation” course, run by Professor Sven Voelpel, and as a member of the judging panel for the final presentations, I found the international mix of students to be a great asset to the discussions.

Courage & Responsibility: Bold decisions define progress

From a daring experiment to an international hub of education and research, Constructor University has always been shaped by courageous, intentional decisions. Buildings once meant for division now host dialogue, discovery, and collaboration – evidence of a community that sees potential where others see limits. Our culture is one of informed decision-making, tested and refined as new knowledge emerges.

For 25 years, these choices – bold and quiet, personal and collective – have built a legacy of learning, discovery, partnership, and resilience. Through name changes and leadership shifts, our essence has remained the same: a place inspired by, run by, and dedicated to creating Constructors. Like our mascot Joana, we remain adaptable, resilient, and strongest when moving together.

The next 25 years will demand decisions that matter – for CU, for science, and for the global communities we serve. In a unique ecosystem of technology, capital, and knowledge, we choose to lead, not watch from the sidelines. Leadership is a decision – and one we commit to again and again.

So here’s to the choices that brought us here, and to the ones that will define what comes next.

Here’s to Constructing the Future.
