That’s where Nicola Pellow came in. An undergraduate at Leicester Polytechnic, Pellow was still an intern at CERN. She was assigned to Berners-Lee’s and Calliau’s team, so they tasked her with building an interoperable browser that could be installed anywhere. The fact that she had no background in programming (she was studying mathematics) and that she was at CERN as part of an internship didn’t concern her much.
