Life


Early years

Brunolf Baade was born in and grew up on the southern edge of Rixdorf (today Neukölln), a densely populated district then just outside the northern perimeter of Berlin. (Rixdorf was incorporated into greater Berlin in 1920.) His father was employed in a small electronics company, later rising to the position of assembly and technical worker. Brunolf had two younger sisters. His mother contributed to the household budget by running a small shop. Baade's father came from farming stock, but his mother's ancestry included teachers and artisans, along with the popular 19th-century poet Hofmann von Fallersleben, an ancestor of whom Brunolf Baade was particularly proud. Baade attended the Emperor Frederick Grammar School (''Kaiser-Friedrich-Realgymnasium'') locally from 1910, successfully completing his school-leaving exam in 1922. When he was 14, his enthusiastic if brief involvement in some of the preparations for revolution, which erupted in post

Building aircraft

Returning to Berlin, Baade resumed his studies, now increasingly focused on the potential of the aircraft business, to which he had been introduced during his stay in South America. He joined the Academic Flying League and started to construct gliders. (Production and operation of powered aircraft in Germany had been restricted under the provisions of the

Once there, however, he loosened his ties with BFW, remaining in the USA for some years, working at various times for Eastern Aircraft,

The Soviet Union

The Soviets had their own plans for postwar Germany. In fall 1945, Baade was mandated by the Soviet Military Administration to reconstruct the Junkers research facilities, using whatever remained of the wreckage in Dessau factory. The physical assets having been removed by the Americans, the Soviets were chiefly dependent on the "intellectual property" that could be extracted from plant personnel. Engineering and production specialists were required to write down everything they could remember. In the end, more than 2,000 written reports were prepared and shipped to the Soviet Union, though as matters turned out, the subsequent research of the Junkers engineers would be of greater value than their memories of the past. Progress resumed on the company's advanced jet-engined designs, and work began on rebuilding the former Junkers factory at Dessau. On 22 October 1946, however, Soviet troops appeared outside the houses of selected company personnel who were given four hours to pack their possessions and prepare for a two-week journey by truck to a village north of Moscow, and close to

, called Podberezye (Подберезье). Some were accompanied by their wives, while for others, their families followed a few weeks later. When they arrived, they were confronted by a large complex of otherwise abandoned military buildings containing a considerable quantity of machinery that the Soviets had managed to gather from various formerly German aircraft manufacturing facilities. Never had any doubt existed that the Soviets viewed formerly German military-industrial assets in their occupation zone as Soviet property, and while their commitment to progress on the advanced aircraft design for which Junkers was known was genuine enough, it now transpired that further work would be undertaken in the Soviet Union. Whether Baade was one of those abruptly transported or whether he was already in the Soviet Union is unclear. In any event, Baade, whose talents for leadership and for charming people were not in doubt, quickly emerged as the leader of the relocated German engineers, and as a man whom the Soviets were in large part prepared to trust. Unlike the other German engineers in Podberezye, Baade was apparently allowed to move freely, and was even seen, early in 1947, on holiday in the

on which serious work began in 1948. The design incorporated innovative ideas on materials and design. As with the earlier project, progress was hampered by the inconsistent nature of support from the Soviets in obtaining materials and permitting the German expatriates the freedom necessary to develop and test the aircraft effectively. By 1951, the OKB-1 150 had been developed into a heavy bomber with a range around 1,500 km and a bomb capacity around 600 kg, but in 1952, this project, too, was abandoned, as resources were again reprioritized.

died, and as the decade unfolded, the political temperature in Moscow and East Berlin started, slowly, to become a little less nervous, and Moscow's approach to its East German ally became less antagonistic. After a period of uncertainty, in December 1953 Baade persuaded the Soviets to permit his team to develop the abandoned OKB-1 150 bomber into a world-class jet-engined passenger aircraft. Holding the German aeronautical engineers in a village north of Moscow made less sense once the decision had been taken to lift the ban on aircraft manufacture in East Germany with effect from 1955. In 1954, Brunolf Baade relocated to East Germany and joined the country's ruling Socialist Unity Party of Germany (SED) / '). By June 1954, the last of the German engineers had been repatriated back to Germany or Austria.


Back in the GDR

After returning the German Democratic Republic with Soviet assent to the passenger jet promised, Brunolf Baade was given responsibility for developing and producing what came to be known as the 152. In terms of stealing a march on the west, political support from the national leadership was enthusiastic, but sources written with the benefit of hindsight nevertheless surmise that Baade had underestimated the challenges. When his 300 aeronautical engineers arrived back from the Soviet Union, not even space was available to accommodate them. No infrastructure remained to support an aeronautical industry in terms of a supply chain, and although enthusiasm was plentiful, no experienced labour pool existed from which to draw workers. High wages in

and elsewhere were sucking the country dry of its skilled workforce. A survey in 1956 found that only 11% of the specialist workers engaged on the project had worked in aeronautics the last time Germany had had an industry, before 1945. In respect of the development work already undertaken in the Soviet Union, Baade no longer had access to the Soviet test pilots who had been permitted to fly the earlier military versions of the plane. He had been forced to leave key technical documentation behind, and never passed over: whether this resulted from overlapping bureaucratic structures in the Soviet system or from some high level decision was never entirely clear. Nevertheless, Baade's connections in the Soviet Union meant that where key components could not be obtained in East Germany, they would be delivered from the Soviet Union. Finance was found for the construction of a new development centre at a former Luftwaffe airfield at

Time-line slippage was inevitable, and a critical constraint clearly would be development of the

To secure continued funding and political support, Baade was committed to a 1958 launch, but when the 152 appeared outside the hangar at Klotzsche for its high-profile "roll-out" in April 1958, the "152-V1", it did so without engines.

The four people on board were killed, and the accident was attributed to pilot error. Much later, more considered verdicts concur around the suspicion that the engines were starved because of issues involving the fuel feed system and/or the 16 rubber fuel bladders positioned in the wings. Aircraft development at the Dresden facility and Pirna engine plant ended formally in 1961. In March 1961, Baade became director of the newly founded Institute for Lightweight construction and the economical use of Materials (IfL), based in Dresden-Klotzsche. He had previously held a position, since 1955, as a lecturer at what was at the time the Faculty for Aeronautical Engineering at the
