1.WhowasJohnSnow?约翰·斯诺（1813-1858),英国医生，19世纪50年代因其对霍乱病源的研究和贡献享誉世界医学界，被公认为流行病学奠基人之一。斯诺1836年起接受正规医科教育，1844年毕业于伦敦大学。1854年伦敦霍乱流行，斯诺通过研究霍乱病死者的日常生活情况，发现了霍乱与饮用不洁水的关系。在他的呼吁下，政府及时关闭了不洁水源，有效制止了霍乱的流行。虽然斯诺没有发现导致霍乱的病原体，但他创造性地使用空间统计学查找到传染源，并以此证明了这种方法的价值。今天，绘制地图已成为医学地理学及传染病学中一种基本的研究方法。“斯诺的霍乱地图”成了一个经典案例。2.HowdidJohnSnowdefeatKingCholera?JohnSnowbegantotestthetheory,usingstatisticsandmaps.
