Biography
Huttenlocher (née Burns) was born in Buffalo, New York. She received her B.A. at the University of Buffalo in 1953, married her husband Peter Huttenlocher in 1954, and had three children. Huttenlocher attended Harvard University for her graduate studies in Psychology, completing her M.A. in 1958 and Ph.D in 1960 under the supervision of Professor Frederick Mosteller. She completed postdoctoral training at Harvard University in the 1960s in the midst of the cognitive revolution. Huttenlocher joined the faculty of the Department of Psychology at the University of Chicago in 1974, after teaching at Teachers College, Columbia University.

Research
Huttenlocher co-authored two books and over 100 research articles on a range of topics including language development, spatial reasoning, memory, and quantitative development. Her book Making space: The development of spatial representation and reasoning, co-authored with Nora Newcombe, provided a comprehensive account of how children actively construct mental models of spatial environments. Her second book Quantitative development in infancy and early childhood, co-authored with Kelly Mix and Susan Levine, focused on how children develop numerical concepts and quantitative reasoning skills.

Huttenlocher was well known for her research on the verbal behavior of parents and teachers in relation to children's language development, focusing on the effects of early input on children's vocabulary growth and their learning of grammar (syntax).
