in the early twentieth century, with mass advertising campaigns to glamorize smoking<br />

of particular br<strong>and</strong>s of cigarettes (Slade 1993). Free cigarettes were distributed in<br />

military rations to allied soldiers in the First <strong>and</strong> Second World Wars.<br />

Collectively, these changes caused a large increase in the number of people smoking<br />

manufactured cigarettes, greater daily consumption of cigarettes, <strong>and</strong> a much greater<br />

surface area of tissues exposed to the carcinogens in tobacco smoke. A dramatic increase<br />

in cigarette smoking occurred first among men in the United Kingdom <strong>and</strong> United<br />

States, <strong>and</strong> later among women. In Britain, nearly 70 per cent of men <strong>and</strong> over 40 per<br />

cent of women between the ages of 25 <strong>and</strong> 59 were currently smoking cigarettes by the<br />

mid-twentieth century (Peto et al. 2000). In the United States, 57 per cent of men, <strong>and</strong> 28<br />

per cent of women, reported current cigarette smoking in 1955, the time of the first<br />

national survey (Haenszel et al. 1956). Despite widespread smoking, little scientific<br />

attention was paid to the negative health effects of cigarettes before the mid-twentieth<br />

century. Rottman had reported a small cluster of lung cancer among tobacco workers in<br />

Leipzig in 1898 (Rottmann 1898). Several correlation studies noted the statistical association<br />

between the rise in cigarette consumption <strong>and</strong> the increasing population rates of<br />

lung cancer in men (Adler 1912; Tylecote 1927; Lickint 1929; Hoffman 1931; Arkin <strong>and</strong><br />

Wagner 1936; Fleckseder 1936). Raymond Pearl described reduced longevity in smokers,<br />

based on family history records at the Johns Hopkins School of Hygiene (Pearl 1938).<br />

Several small case-control studies of smoking <strong>and</strong> lung cancer published before 1950<br />

found a higher percentage of smokers among patients with lung cancer than with other<br />

diseases (Muller 1939; Schairer <strong>and</strong> Schioninger 1943; Wassink 1948). A series of skintesting<br />

experiments in rabbits were either negative (Leitch 1928; Passey 1929), or demonstrated<br />

some increase in skin tumors (Roffo 1931; Cooper et al. 1932) after prolonged<br />

contact with tar extracts from cigarettes. However, the tumorigenicity of tobacco extracts<br />

appeared to be less than that of coal tar, <strong>and</strong> interpretation of the animal experiments<br />

was complicated by controversy about the temperature at which the tar was extracted<br />

from tobacco for the animal experiments, compared to the typical burning conditions in<br />

a cigarette (Doll 1998b). Only in Germany were doctors <strong>and</strong> the Nazi political authorities<br />

concerned about the potential cardiovascular <strong>and</strong> reproductive toxicity of ‘nicotinism’,<br />

which was not at the time based on sound scientific evidence (Doll 1998b).<br />

It was the extraordinary rise in lung cancer that began early in the twentieth century<br />

among men in the United Kingdom, later among men in other countries, <strong>and</strong> subsequently<br />

in women, that finally drew serious attention to the hazards of smoking (Doll<br />

<strong>and</strong> Hill 1950; Wynder <strong>and</strong> Graham 1950). Lung cancer had hitherto been a rare disease.<br />

The increase in the age-st<strong>and</strong>ardized death rate from lung cancer among men in Engl<strong>and</strong><br />

<strong>and</strong> Wales had begun by 1912 <strong>and</strong> accelerated sharply after the First World War (Doll<br />

<strong>and</strong> Hill 1950). The number of lung cancer deaths recorded per year in Engl<strong>and</strong> <strong>and</strong><br />

Wales increased approximately 15-fold over the 25-year period between 1922 <strong>and</strong> 1947,<br />

far in excess of the increase in the size, or longevity of the population. In the United<br />

States, where cigarette smoking began later <strong>and</strong> vital statistics data on mortality did not
