In 1987 the Electron Microscopy Society of America (EMSA) going to drive important scientific discoveries across wide areas under the leadership of J. P. Revel (Cal Tech) initiated a major of physiology, cellular biology and neurobiology. They had been program to present a discussion of recent advances in light looking for a forum in which they could advance the state of microscopy as part of the annual meeting. The result was three the art of confocal microscopy, alert manufacturers to the limยญ special LM sessions at the Milwaukee meeting in August 1988: itations of current instruments, and catalyze progress toward The LM Forum, organized by me, and Symposia on Confocal new directions in confocal instrument development. LM, organized by G. Schatten (Madison), and on Integrated These goals were so close to those of the EMSA project that Acoustic/LM/EM organized by C. Rieder (Albany). In addition, the two groups decided to join forces with EMSA to provide there was an optical micro-analysis session emphasizing Raman the organization and the venue for a Confocal Workshop and techniques, organized by the Microbeam Analysis Society, for NSF to provide the financial support for the speakers expenses a total of 40 invited and 30 contributed papers on optical techยญ and for the publication of extended abstracts
