The Eleventh American Peptide Symposium was held on the San Diego campus of the University of California in picturesque La Jolla on July 9-14, 1989. More than 1100 participants from around the world came to attend a scientific program comprised of an assortment of oral presentations, posters and exhibits. Most rewarding to us was the regular attendance at all the scientific sessions by our registered guests despite the beautiful scenery offered by La Jolla and San Diego county. Indeed for all of us, the purpose of the biennial American Peptide Symposium is to try to keep up with a fast...
