The Camden School for Girls (CSG) is a comprehensive secondary school for girls, with a co-educational sixth form, in the London Borough of Camden in north London. It has about one thousand students of ages eleven to eighteen, and specialist-school status as a Music College. The school has long been associated with the advancement of women's education.Founded in 1871 by the suffragist Frances Mary Buss, who also founded North London Collegiate School, the Camden School for Girls was one of the first girls' schools in England. Although not a fee-paying school by then, girls in the mid-20th century wore a traditional uniform of dark green, with blue and green striped ties. The blazer badge showed a type of ancient sailing ship called a "buss" to commemorate the founder's surname, with the motto 'Onwards and Upwards'. Although no entry exams were held, in its pre-comprehensive era, entrance was by interview.One of its most formative headmistresses, Doris Burchell, took on the school in the post war years and developed its renowned strengths in both science and music, overseeing a massive amount of new building on the site. The Sir John Cockcroft science wing was built from funds raised by many means, including a series of Celebrity Concerts held at the school and involving many eminent musicians. A grammar school for much of the 20th century, it became comprehensive in 1976, although only year by year. It was not fully comprehensive until 1981. The school was damaged in the war but rebuilt in 1957, the architect being John Eastwick-Field OBE. In 1973 the assembly hall roof collapsed following deterioration of its roof beams due to problems with the high-alumina cement concrete used.
