In the vibrant, though often complex, landscape of West German post-war scientific recovery, the Berthold Seliger Forschungs- und Entwicklungsgesellschaft mbH (BSFEGmbH) emerged in 1961. This company was the brainchild of Berthold Seliger, a distinguished West German rocket technical designer, whose professional lineage traced back to the esteemed theoretician Professor Dr. Eugen Sänger, a pioneer known for his foundational work in rocket propulsion and his visionary "Silverbird" antipodal bomber concept. Seliger's venture positioned itself at the forefront of private rocketry, dedicated to the development and construction of prototype sounding rockets.

These experimental rockets found their launchpad near the historic coastal town of Cuxhaven, a location with its own significant history in German rocket development, offering ample space and clear firing ranges over the North Sea. The BSFEGmbH fostered a robust collaborative relationship with the Hermann-Oberth-Gesellschaft, a society named after the celebrated Austro-Hungarian-German rocket theoretician Hermann Oberth, which played a crucial role in promoting rocketry and spaceflight among enthusiasts and professionals alike. Berthold Seliger himself was an active member of this influential society, underlining the strong ties between his company's private endeavors and the broader, if often amateur, rocketry movement in West Germany.

Pioneering Launches and Technical Milestones

The company quickly moved from concept to demonstration, achieving several notable milestones in its brief operational history. The very first rocket to be developed and launched by BSFEGmbH was an enhanced iteration of the Kumulus, a design likely originating from or inspired by the earlier amateur rocket community. This improved Kumulus made its maiden flight on November 19, 1962, successfully reaching an impressive altitude of 50 kilometers, a significant achievement for a privately developed rocket at the time.

Building on this success, BSFEGmbH demonstrated its escalating technical prowess the following year. On February 7, 1963, they launched a more advanced two-stage rocket, which ascended to a maximum height of 80 kilometers. Their ambition culminated on May 2, 1963, with the launch of a sophisticated three-stage rocket. This particular vehicle achieved a remarkable flight altitude exceeding 100 kilometers, a feat that may well represent the highest flight altitude attained by any rocket constructed in post-war Germany, a testament to Seliger's engineering vision. Throughout these pioneering launches, the vital telemetry signals from the rockets were successfully received and monitored by the observatory in Bochum, located approximately 300 kilometers south-southwest of Cuxhaven, demonstrating a degree of scientific collaboration and technical sophistication in their operations.

A Shift Towards Controversy and the End of an Era

Following these impressive early successes in May 1963, the focus of BSFEGmbH began to shift. The company dedicated its efforts to refining the steering systems of its rockets, an essential step for any advanced rocketry. Concurrently, discussions and considerations turned towards the potential for developing rockets with military applications. This shift marked a critical turning point for the company, as post-war Germany, especially West Germany, operated under strict Allied laws and regulations concerning the development of military weapons, particularly long-range ballistic missiles, a legacy of the Second World War.

The underlying tensions came to a head on December 5, 1963, when BSFEGmbH conducted a flight demonstration of their rockets for military staff from various non-NATO countries. While the rockets were intentionally launched with a reduced amount of propellant, a measure taken specifically to avoid directly violating Allied laws concerning military rocket development in Germany, and were not yet truly fit for military use, this demonstration nevertheless drew intense scrutiny. From this point onward, the rocket experiments conducted by both the Hermann-Oberth-Gesellschaft e.V. and the BSFEGmbH were viewed with considerable suspicion by the Allied powers, who were keenly sensitive to any potential resurgence of German military aerospace capabilities.

Ultimately, these pioneering experiments were brought to an abrupt halt in 1964. A temporary injunction was issued, which, remarkably, remains valid to this day, effectively prohibiting such private rocket development. The immediate catalyst for this injunction was a tragic fatal accident that occurred at a separate rocket demonstration by Gerhard Zucker in Braunlage. It is crucial to note, however, that Gerhard Zucker had absolutely no affiliation or cooperative ties with either the BSFEGmbH or the Hermann-Oberth-Gesellschaft e.V., and indeed, he was known to have a poor reputation among the members of these societies due to his less stringent safety practices. Despite this lack of connection, Zucker's incident provided a convenient and compelling reason for authorities to clamp down on all private rocket experimentation in West Germany, particularly given the growing unease surrounding the potential military implications of projects like those undertaken by BSFEGmbH.

FAQs About BSFEGmbH and German Post-War Rocketry

What was the Berthold Seliger Forschungs- und Entwicklungsgesellschaft mbH (BSFEGmbH)?

The BSFEGmbH was a West German company founded in 1961 by rocket technical designer Berthold Seliger, dedicated to the development, construction, and launch of prototype sounding rockets.

Who was Berthold Seliger?

Berthold Seliger was a West German rocket technical designer and the founder of BSFEGmbH. He had previously worked as an assistant to the eminent theoretician Professor Dr. Eugen Sänger, a significant figure in early rocket propulsion theory.

What kind of rockets did BSFEGmbH develop?

BSFEGmbH focused on developing and building prototypes of sounding rockets, including an improved version of the Kumulus and more advanced two-stage and three-stage designs.

Where were the rockets launched?

The company's rockets were launched from near Cuxhaven, a coastal town in northern Germany, offering a suitable location for such experimental flights.

What was the significance of BSFEGmbH's three-stage rocket?

Launched on May 2, 1963, this rocket achieved a flight altitude of over 100 kilometers, a remarkable feat that may represent the highest altitude attained by any rocket built in post-war Germany.

Why did BSFEGmbH's activities become controversial?

After May 1963, BSFEGmbH began considering developing rockets for military use. A demonstration for non-NATO military staff in December 1963, despite using reduced propellant, drew significant suspicion from Allied powers due to strict post-war regulations on German military development.

Why were their rocket experiments ultimately discontinued?

The experiments were discontinued in 1964 by a temporary injunction, which remains valid today. This decision was triggered by a fatal accident at an unrelated rocket demonstration by Gerhard Zucker, which provided authorities with a reason to halt all private rocket development, especially given the earlier military implications of BSFEGmbH's work.

Was Gerhard Zucker affiliated with BSFEGmbH?

No, Gerhard Zucker had no affiliation or cooperative relationship with BSFEGmbH or the Hermann-Oberth-Gesellschaft e.V. In fact, he was known to have a poor reputation with members of these societies.
