Immanuel Kohn, a corporate partner at Cahill Gordon & Reindel and longtime chairman of the firm’s executive committee, died yesterday at his Princeton, N.J., home from lung cancer. He was 86.

Kohn joined Cahill in 1953 and became a partner in 1962. He chaired the firm’s executive committee for 15 years, from 1990 through December 2005. Called "Ike" by family and friends, he became senior counsel when he stepped down as chairman.
