The proceeds from his work as a consulting chemist allowed McCrone to endow the Emile M Chamot Professorship of Chemistry at Cornell, named in honor of McCrone's university mentor.

For more than thirty years McCrone edited and published The Microscope, an international quarterly journal of microscopy that had been established in 1937 by the British microscopist Arthur L E Barron.

Walter McCrone wrote more than 400 technical articles along with sixteen books or chapters.

Walter McCrone is credited with expanding the usefulness of the optical microscopy to chemists, who had previously regarded it as primarily a tool for biologists.

The Particle Atlas, which was written in collaboration with other staff members of Walter McCrone Associates, appeared in a six-volume second edition in 1973.

Walter McCrone served on the board of directors and as president of the Ada S McKinley Community Services, a nonprofit social services agency in Chicago.

Walter McCrone continued to defend his results and to insist that polarized light microscopy, in which he was the only expert among the original members of STURP, was the correct technique to apply to the study of the Shroud.

Walter McCrone re-stated and summarized his evidence that the Shroud was painted in an article published in 1990 in the journal Accounts of Chemical Research.

Walter McCrone later wrote a book on the subject, Judgment Day for the Shroud of Turin, published in 1996 by the McCrone Research Institute's Microscope Publications and re-issued in 1999 by Prometheus Books.
