The three original insights: John Snow issued the first warning on the prolonged use of oxygen in the new-born in his 1841 paper on “Asphyxia and Resuscitation of Still-born Children”.

In 1850, Snow was the first to advocate and use chloroform in the treatment of status asthmaticus.

The first description of “Publication Bias”, in the medical literature, was by Snow in 1858 in “On Chloroform and other Anæsthetics: Their Action and Administration”.

The misconception. Snow believed that death during chloroform anaesthesia was caused by “air too heavily charged with chloroform” and could be prevented by “judicious” as opposed to “freely” administration of the vapour.
