The company was created by Otto Winzen and his wife Vera Habrecht. Vera, eventually an accomplished balloonist herself, borrowed money from her parents to help start Winzen Research. She held over two-thirds ownership of the company and became its vice president. Vera supervised and trained her "balloon girls" to handle polyethylene

Winzen Research also designed and built gondolas. The company supplied both the balloon and gondola that were used for the 1961 Strato-Lab V flight that set current altitude record for manned balloon flights. The balloon was constructed of polyethylene plastic measuring only 0.001 inch (0.0254 mm) thick. At 10 Mcuft, the balloon envelope was the largest that had ever been successfully launched, expanding to 300 feet (91.4 m) in diameter when fully inflated. Beneath the balloon hung a large parachute and then the gondola. Winzen Research designed a unique gondola for the flight. To control temperature, the gondola was protected by special venetian blinds, but otherwise open to space. The venetian blinds had light and dark sides. The light side could be turned outwards to cool the cabin while the dark side could be turned outward to warm the cabin. Balloon, parachute, gondola, and a trailing antenna made a craft close to 500 feet (152.4 m) tall.
