Altom suicide

. Altom's suicide caused controversy because he explicitly blamed Corey, his research advisor, for his suicide. Corey was devastated and bewildered by Altom's death. Altom cited in his 1998 farewell note "abusive research supervisors" as one reason for taking his life. Altom's suicide note also contained explicit instructions on how to reform the relationship between students and their supervisors.

, Altom's suicide note indicated fear that his career hopes were doomed, but The Globe also cited students and professors as saying that Altom actually retained Corey's support.

Corey Group Members

As of 2010, approximately 700 people have been Corey Group members. A database of 580 former members and their current affiliation was developed for Dr. Corey’s 80th birthday in July, 2008.

.
Corey wrote:

“On May 4, 1964, I suggested to my colleague R. B. Woodward a simple explanation involving the symmetry of the perturbed (HOMO) molecular orbitals for the stereoselective cyclobutene → 1,3-butadiene and 1,3,5-hexatriene → cyclohexadiene conversions that provided the basis for the further development of these ideas into what became known as the Woodward-Hoffmann rules.”

This was Corey's first public statement on his claim that starting on May 5, 1964 Woodward put forth Corey’s explanation as his own thought with no mention of Corey and the conversation of May 4. Corey had discussed his claim privately with Hoffmann and close colleagues since 1964. Corey mentions that he made the Priestley statement “so the historical record would be correct".

Corey's claim and contribution were publicly rebutted by Roald Hoffmann

. In the rebuttal, Hoffmann states that he asked Corey over the course of their long discussion of the matter why Corey did not make the issue public. Corey responded that he thought such a public disagreement would hurt Harvard and that he would not “consider doing anything against Harvard, to which I was and am so devoted.” Corey also hoped that Woodward himself would correct the historical record “as he grew older, more considerate, and more sensitive to his own conscience.”
Woodward died suddenly of a heart attack in his sleep in 1979.
