  "description": "Helen P. Galt's research notebook for the 1957 academic year. Marbled boards, ruled grid; contained three trials of her carrot chromatography column showing an orange band whose retention time and pH-invariance matched R. Penn's claimed 'novel anthocyanin congener' from beet extract — the cross-comparison that would have invalidated Penn's thesis. Left unlocked in the second-from-top drawer on the right of her lab desk Friday evening 4 October 1957. Missing Sunday evening 6 October when Helen returned to fetch it for Monday's seminar."
