– was now engaged in the manufacture of equipment deemed important to the German war effort: precision optics for binoculars, periscopes, telescopic sights (for sniper rifles, for example), and theodolites for directing artillery. Although these products consumed the bulk of the companies resources, some regular product development was still possible, and work on tempered glass lenses as well as flash synchronization continued, albeit on a small scale. The cameras were used inter alia in military reconnaissance. As Braunschweig was one of the centres of the German armaments industry, it was subjected to frequent, sometimes heavy aerial bombardment, which seriously damaged the city. On 1 and 15 January 1944, and again on 13 August, Rollei too suffered air raid damage to its factories. By the time the war ended on 12 April 1945, almost 65% of its plant and machinery had been destroyed. The post-war period After the war, Braunschweig ended up in the British occupation zone. The allied occupying forces wanted Rollei to survive as a company, even helping it procure lenses from Zeiss, which had ended up in the Soviet occupation zone. Franke & Heidecke started over with 72 workers, and by Christmas 1945 the workforce had grown to 172 employees. Everything the company made in 1945 was delivered to the British Ministry of Defence. The difficult supply situation forced Rollei into using lenses from the West German manufacturer Schneider as well. However, this was not a problem as Schneider's quality control was equal to that of Zeiss. Paul Franke's untimely death in the spring of 1950 had serious consequences for the company though. Not only did his passing mark the end of an era for Rollei, the loss of his business acumen also led the company to the edge of ruin on more than one occasion. 1950 to 1963 - Horst Franke era The golden era After Paul Franke's death, his son Horst Franke succeeded him. Overall, he proved to be less effective as a manager than his father. In particular, he lacked the flexibility required to adapt to changing circumstances; for example, he failed to reduce the workforce in difficult times, whereas Paul Franke had done so immediately at the onset of the war. To begin with, Rollei had no real competition, which yielded ever increasing sales of its cameras. In the 1950s, almost every press photographer owned a Rolleiflex, and quite a few amateurs did as
