The Author 



WILLIAM H. FRANDSEN is a Research Physicist stationed at the 

 Northern Forest Fire Laboratory in Missoula, Montana. He 

 received his B.A. in physics and mathematics from Lewis 

 and Clark College in 1954, and his M. A. in physics from the 

 University of Oregon in 1960. Frandsen was employed from 

 1955-1967 as a physicist at the Naval Weapons Center at 

 China Lake, California. While there he was involved in two 

 fields of study: infrared detection systems and the effects of 

 ultrasound on metals. Since 1967, Frandsen has been with 

 the Fire Fundamentals research work unit at the Northern 

 Forest Fire Laboratory, where he is responsible for the 

 technical planning and execution of research concerned with 

 the thermodynamics of the fire and its interaction with the 

 fuel complex. 



The author thanks Mr. Merlin Brown, Electronics Techni- 

 cian at the Northern Forest Fire Laboratory, for his extreme 

 care in fabricating and implanting the fine-wire thermo- 

 couples used in this study.
