I have long been Born in Brussels, Belgium on December 31, 1921 and for involved in studying his research and life, first as a student in 59 years a professor at Columbia University, Gilbert Stork is need of synthetic methodologies for my graduate research[11] one of organic chemistrys most beloved and simultaneously and later, much later, as a historian of chemistry (Figure 1).[12] eminent artists.[1–3] His creativity extends far beyond his chemical successes. He has a special way, an aura that is and has been unique in our community of scholars and—yes— unique among a group of already rather eccentric practitioners. Many celebrations highlighted 2011, the International Year of Chemistry. Some of these honored Gilberts reaching the wonderful age of 90. See, for example, Gilberts own recol- lections[4] published in an issue of Tetrahedron honoring his 90th birthday and in a broad review of his chemistry published a decade ago.[5] The reader is urged to read Gilberts own articles. Why so much attention on Gilbert Stork? It is because Gilbert has been one of the leaders of synthetic organic chemistry for decades. He has propelled the discipline of Figure 1.

Woodward collection organic chemistry throughout the broader community of at the Harvard University Archives, August 2009. chemists by virtue of his research and scholarship, his legacy of graduate students and postdoctoral fellows, and his demeanor. Stork is not only one of the most esteemed and (I might still be in graduate school had it not been for the Stork well-liked of chemists; he has mentored a cadre of some of the enamine reaction.[13,14]) Thus, I wanted to make some special disciplines most successful organic chemists whose loyalty to contribution toward the celebration of Gilberts life. What and even reverence for this fine gentleman is extraordinary. As better way, I realized, then assembling and sharing Gilberts stated by one of his former students, “Gilbert is a global own words and deeds. So, what follows is mostly a collection of treasure!

Some were important, but not that much. For instance, the prostaglandin synthesis from glucose [*] Dr. J. I.
