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 http://en.wikipedia.org/wiki/Gas_mask—Preceding unsigned comment added by 22.214.171.124 (talk) 11:21, 15 September 2009 (UTC)
