John B. Christian
John Christian was working as an Air Force, Materials Research, Engineer, when he invented and patented new lubricants, used in high flying aircraft and NASA space missions. The lubricants worked well under a wider temperature range than previous products, from minus 50 to 600 degrees. They were used in the helicoptor fuel lines, astronaut's back-pack life support systems, and in the four-wheel drive of the "moon-buggy".
