<Gerald Jay Sussman> is a <computer scientist> whose work includes the design and explanation of systems expressed as programs. With <Hal Abelson> and <Julie Sussman>, he authored <Structure and Interpretation of Computer Programs by Harold Abelson and others>, a text that develops <programming abstraction>, <recursion> and models of program execution through <Scheme>.<Structure and Interpretation of Computer Programs by Harold Abelson and others>[Second-edition byline and section 1.2]{ref}
One useful distinction in the text is between the shape of a procedure's source and the computation it generates. A syntactically recursive procedure can produce an iterative process when no deferred operations accumulate. That makes the execution model, rather than the presence of a self-call alone, central to reasoning about storage.<Structure and Interpretation of Computer Programs by Harold Abelson and others>[Section 1.2.1, Linear Recursion and Iteration]{ref}
