25 Years of Decision Making

Celebrating 25 Years of Constructor University

Our 25^th year anniversary is a year-long celebration of what makes CU like no other university in the world – and an opportunity to highlight the impact Constructors have had on global discourse, research, and our connection to Bremen and beyond.

The decisions that shaped our first 25 years created the international, interdisciplinary foundation for the next era of discovery. By marking this milestone, we are not only reflecting on our history – we are demonstrating why it matters for what comes next: advancing knowledge and technology to streamline science, research and learning, strengthening our ties with our alumni, connecting with the broader global academic and industry community, reinforcing identity among faculty and staff, while empowering the next generation of researchers, innovators, and leaders in computer science, business, and the physical sciences.

Chancellor Turgut Tülü

25th Anniversary Message

Germany urgently needs universities such as the one being inaugurated in Bremen today: that is, institutions of higher learning that are modern, performance-oriented, independent of the reins of state bureaucracies, interdisciplinary, and, at the same time, international.

Helmut Schmidt, Ex-chancellor of Germany

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 actively shaping the present, and those who will lead the charge into a new era of knowledge-driven transformation.

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)

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)

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)

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)

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

25 years ago, visionaries imagined a new kind of university in Bremen, built on global collaboration and the belief that advancing knowledge and technology is essential to making science and learning more effective. Although not yet called Constructor University, our predecessors shared a vision to rethink and reconstruct higher education. In 2026, we celebrate choices made by faculty, students, and leaders who helped pave the way for Constructor University to become an internationally-renowned institution at the forefront of shaping the future.

Raymond O. “Ronny” Wells Jr.

“Ronny” is currently the Chairman of the Board of the Constructor University Foundation of America, a Distinguished Professor of Mathematics at Constructor University, and an Emeritus Professor of Mathematics at Rice University. An Alexander von Humboldt Prize winner, “Ronny” is often referred to as “employee zero” and a founding father of International University Bremen (IUB), where from 2001 to 2005, he served as IUB’s first Vice President for External Affairs.

Malcolm Gillis

Stephen Malcolm Gillis (1940–2015) was the 6th President of Rice University (1993–2004), known for expanding research, strengthening international partnerships, and supporting innovative higher-education models. He played a crucial founding role in establishing International University Bremen, serving on early boards and shaping its academic concept and global orientation.

Henning Scherf

Dr. Henning Scherf, a prominent SPD politician, served as Mayor and President of the Senate of the Free Hanseatic City of Bremen from 1995 to 2005. A long-standing advocate for education and research, he was instrumental in mobilizing governmental and civic support for the founding and early development of International University Bremen.

Reimar Lüst

Professor Reimar Lüst (1923–2020) was one of Germany’s most distinguished scientists, known for his leadership at the Max Planck Society, the European Space Agency (ESA), and his influential role in international science policy. As one of the most prominent scientific supporters of IUB, he contributed credibility, guidance, and high-level advocacy during the university’s foundation phase.

Fritz Schaumann

A lifelong public servant, Fritz Schaumann (1946-2017) served nearly a decade as Germany’s Deputy Minister for Education and Research. He played a key role in securing political support for the founding of IUB and became the university’s first President (1999–2006), guiding it through its formative years.

Joachim Treusch

Dr. Joachim Treusch, an accomplished physicist and research leader, served on the university’s Board of Governors and later became President of Jacobs University (2006–2012). He was essential in bringing Klaus Jacobs on board, helping secure the transformative philanthropic investment that reshaped the university’s future.

Klaus J. Jacobs

Klaus J. Jacobs (1936–2008), a Swiss-German entrepreneur and philanthropist, was widely known for his leadership in global food and coffee industries and for major philanthropic contributions to youth development and education. Following his €200 million donation in 2006, the university was renamed Jacobs University in his honor.

Dr. Serg Bell

Businessman, entrepreneur and investor, Dr. Bell and the Constructor Group acquired the university in 2022. Driven by the global advancement of science and education globally, he seeks to realize this vision through various initiatives. He is founder of Acronis and currently the Vice Chairman of the Board of Governors of Constructor University.

Courage & Responsibility: Bold decisions that define progress

From the Constructors whose early work laid the foundations of teaching and innovation that that define us today, to researchers who pursued questions others overlooked and students who crossed borders to shape their futures, our history is not only about our accomplishments, but about what it enabled: a university positioned to contribute to the next generation of breakthroughs that will reshape the future.

Our community is one of informed decision-making, tested and refined as new knowledge emerges, and increasingly oriented toward disciplines that shape the future: computer science, business systems, and the physical sciences. 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.

The past has built the foundation for the next phase of our mission—advancing knowledge and technology to make science, research, and learning more effective, and empowering students from around the world to become the next generation of scientists, professionals, and leaders.

The next 25 years will demand decisions that matter—for Constructor University, 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.

As our ecosystem grows to span research, education, industry collaboration, and innovation platforms, we continue to act on the vision of the Constructors who came before us, turning knowledge into proficiency, and proficiency into impact.

So here’s to the choices that brought us here, and to the ones that will define what comes next. And to the next 25 years of transforming knowledge into the foundations of future technologies, future understanding and future leaders.

Here’s to Constructing the Future.

Today, Constructor University is a top-ranked private university with more than 2000 students from over 120 countries.
Developments in private education — globally, across Europe, and in Germany — demonstrate the important role private institutions play in complementing public colleges and universities. The vision shared by the founders of IUB/JUB/CUB 25 years ago – that knowledge is key for our society & pioneers in educational concepts are a necessity for it – is still our mission today.

Over the past years, we have developed an excellent relationship with Constructor University, based on trust and communication. In the future, we shall continue to support young people together. The transdisciplinary and intercultural concept of the still relatively young, rapidly growing university in the north of Bremen not only offers an excellent academic education, but also conveys skills and values for a conscious, tolerant, and peaceful coexistence worldwide. Our aim is that young people will leverage the gained knowledge, competence, and experiences for the benefit and development of their home countries.

In line with the vision of the founder, Joachim Armerding, the foundation places particular emphasis on supporting educational institutions with a strong professional and technical focus. Given the international character of today’s student community and the global network of the HANSA-FLEX Group – headquartered in Bremen – the foundation actively encourages broad-based educational support with both local and international impact.

Thorsten Armerding – Member of the Executive Board, HANSA-FLEX Stiftung

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. As an advocate of the view that “financial education” is a key cornerstone of a person’s life, I seek to engage with young people in order to pass on my knowledge, which is based on a solid banking education, a long-standing international career in investment banking, and start-up experience.

Birgit Nonnenprediger – Generationen Finanzcoach, Switzerland

Constructor University represents a unique opportunity for us to bring international talent directly to Bremen, sustainably strengthening the diversity and innovative power of our region. As a company that relies on highly qualified professionals, we value the university as a bridge between academic excellence and real-world practice – giving us access to outstanding international graduates who enrich our teams. We are particularly passionate about helping young people take their first steps into professional life and offering them a future here in Bremen. Supporting this connection between university, business, and city is, for us, not only an investment in our company's future, but in the entire Bremen region.

Oliver Groß – CEO, Nehlsen AG

While today’s name differs from the one in the year of foundation, the spirit lives on: private initiative continues to create space, inspiration, and motivation for excellent international research. The outstanding reputation and strong scientific credibility of Constructor University define Bremen’s profile as a leading research location. Creating momentum today in order to shape tomorrow lasts as a guiding principle.
