I have reverted an attempt to delete verifiable information on the work of Haldane, which may be an attempt at vandalism. Peterlewis (talk) 19:07, 14 April 2008 (UTC)

Gas Mask[edit]

This article claims that John Scott Haldane invented the gas mask. However that is a mis-statement of what the original source says. Proof that the gas mask predates this man can be found on the wikipedia page for gas-mask —Preceding unsigned comment added by (talk) 11:21, 15 September 2009 (UTC)
