Knorr was born in Frankfurt and raised in the 1960s in San Juan, Puerto Rico. In the 1970s, she moved to Great Britain where she has lived ever since. Knorr is a graduate of the Polytechnic of Central London, and has an MA from the University of Derby. She is Professor of Photography at the University for the Creative Arts. Knorr's work explores Western cultural traditions, mainly British society, with widely ranging topics, from lifestyle to animals. She is interested in conceptual art, visual culture, feminism, and animal studies, and her art maintains connections with these topics. Between 1979 and 1981 Knorr produced Belgravia, a series of black and white photographs each accompanied by a short text, typically critical to the British class system of the time. Subsequently, she produced Gentlemen, a series consisting of photographs of gentlemen's members clubs and texts taken from parliamentary speeches and news reports. In these series, Knorr investigated values of the English upper middle classes, comparing them with aristocratic values. In 1986, the series Connoisseurs was made in color. The series incorporates staged events into English architectural interiors. Between 1994 and 2004, Knorr photographed fine art academies throughout Europe, which resulted in the series Academies. In 2008, she traveled to Rajasthan and took a large series of photographs, predominantly showing Indian interiors, often with animals from Indian folklore inside. She subsequently became a frequent traveller to India, visiting the country 15 times between 2008 and 2014. She mentioned that most of the buildings in India were never photographed, and they are not less interesting than common tourist attractions. From 2014 to 2015, one room of Tate Britain hosted an exhibition of her photographs of "posh west Londoners in domestic settings and portraits of members at a gentlemen's club".
