Martin Hetzel (Bristol Royal Infirmary)

Pioneered work on diurnal variation of peak expiratory flow in asthmatics, including observations when asthmatics were prevented from sleeping, and when kept horizontal all day, to find out whether sleep or posture was the main trigger for diurnal variation (sleep won).

Martin is involved with the following papers on occupational asthma.
