@amoroso Did you Peter Deutsch's IDE from 1968?

"Peter Deutsch wrote a structure editor in Lisp for editing Lisp programs."

Pretty early for a structure editor.

@dougmerritt Interlisp already had a structure editor in 1974 and possibly earlier:

It was inspired by Deutsch's editor:

@dougmerritt This is a preliminar guide to his structure editor for LISP 1.5 Deutsch published in 1967:

https://softwarepreservation.computerhistory.org/LISP/bbnlisp/W-21_LISP_Editor_Apr67.pdf

The paper mentions Warren Teitelman extending the editor at BBN. Presumably with BBN Lisp which became Interlisp in 1973.
