Who documented a method for recording people's images of the city in his book?

The correct answer centers around Kevin Lynch, whose influential work in urban design prominently features the concept of people's images of the city. In his book "The Image of the City," published in 1960, Lynch introduced a systematic method for observing and analyzing how individuals perceive urban environments. He emphasized the importance of mental maps, which are cognitive representations of one's surroundings shaped by personal experiences and interactions.

Lynch identified key elements that contribute to a city's image, such as paths, edges, districts, nodes, and landmarks. By documenting these elements and how people navigate and understand their urban environments, Lynch provided a framework for urban planners and architects to create more legible and cohesive cities. His work laid the groundwork for future studies in environmental psychology and urban design, making it significant in understanding the relationship between people and their urban spaces.

The other choices represent significant contributors to urban planning and architecture but do not specifically focus on the method of recording people's imagery of the city in the way Lynch did.
