History
MSR began as a newsletter in 1969 that covered topics around mountaineering safety.[1] In 1973, Larry Penberthy (1916–2001)[2] developed the MSR Model 9 camp stove, a design which used white gas and was relatively fearsome in cold weather.[3] He separated the stove burner from then small fuel tanks, and then pressurized auxiliary fuel bottles as the tank, and used a better wind screen. Cold weather mountaineers loved it because it was great for melting ice and snow into water.
