Lewis Aron (December 21, 1952 – February 28, 2019)[1] was an American psychoanalyst and psychotherapist, teacher and lecturer on psychotherapy and psychoanalysis who made contributions particularly within the specialty known as relational psychoanalysis.

His 1996 volume A Meeting of Minds: Mutuality in Psychoanalysis and his (1999) edited volume with Stephen Mitchell, Relational Psychoanalysis: The Emergence of a Tradition are considered[by whom?]

[citation needed] Together with Adrienne Harris, he edited the Relational Perspectives Book Series, which has published many of the texts in the field.

Due in large measure to the seminal work of Stephen Mitchell, the term "relational psychoanalysis" grew and began to accrue to itself many other influences and developments.

[5] Various tributaries—interpersonal psychoanalysis, object relations theory, self psychology, empirical infancy research, and elements of contemporary Freudian and Kleinian/Bionian thought—flow into this tradition, which understands relational configurations between self and others, both real and fantasized, as the primary subject of psychoanalytic investigation.
