Asbestos has been proven to cause fatal disease after long term exposure.

Factories in the UK showed initial warning signs (many sufferers of bronchial and lung problems) correlated with asbestos in the workplace. Issues were raised by female inspectors (due to the times were not given sufficient credibility of their work)
Experiments with rats in 1911 confirmed the health risks and factory department pressed for the installation of exhausts
1928 Merewether and C.W. Price concluded that 66% of workers with 20+ years of service suffered from asbestosis - a likely underestimate as only current employees were examined.
Studies post 1955 showed that cigarette smoke and asbestos = double whammy lung cancer.
Mesothelioma (rare lunch lining cancer) was sucessfully atributed to asbestos in 1960, with very small exposure needed for high risk (months rather than years).
