The Journal News (and a number of Catholic blogs) report this sad news:
Smith, 69, was a Yonkers native who grew up in St. Denis parish.
He was ordained a priest in 1966 and shortly thereafter was chosen by Cardinal Terence Cooke to pursue a doctorate in moral theology and return to teach at his hometown seminary.
Smith became a leading Catholic spokesman on issues like abortion, reproduction, euthanasia, stem-cell research and cloning.

Monsignor Smith was, for many years, a contributing editor to Homiletic & Pastoral Review, which is published by Ignatius Press and edited by Fr. Kenneth Baker, S.J.
The Dawn Patrol has some links, including a YouTube video of Monsigner Smith lecturing on the "Moral Magisterium of Pope John Paul II." And John Mallon has posted a 1995 interview he did with Monsignor Smith about contraception and other moral issues that is definitely worth reading.
