The Science family mourns longtime copyeditor Jeffrey Cook, who died unexpectedly last month. Jeff joined AAAS in 1994. He was a true perfectionist and cared deeply about language, editing, and scientific communication. Thousands of Science papers published over the past three decades are clearer and more accurate because of Jeff’s meticulous dedication to his craft. He deftly transitioned from the hardcopy era to the world of online publication. Beyond being a mainstay of the Editorial team, Jeff was an accomplished musician and multi-instrumentalist. When Science launched its weekly podcast in 2007, Jeff composed the theme music, which still welcomes listeners to this day. Jeff was kind, talented, and thorough. He will be missed.
