Boss Wants Too Much

For thirty years, Johnson had arrived at work at 9A.M. on the dot. He had never missed a day and was never late.
Consequently, when on one particular day 9 A.M. passed without Johnson's arrival, it caused a sensation. All work ceased, and the boss himself, looking at his watch and muttering, came out into the corridor.
Finally, precisely at ten, Johnson showed up, clothes dusty and torn, his face scratched and bruised, his glasses bent. He limped painfully to the time clock, punched in, and said, aware that all eyes were upon him, "I tripped and rolled down two flights of stairs in the subway. Nearly killed myself."
And the boss said, "And to roll down two flights of stairs took you a whole hour?"

Vladimir Nikolayevich Ipatieff

Born 21 Nov 1867; died 29 Nov 1952 at age 85.Russian-American chemist who was one of the first to investigate high-pressure catalytic reactions of hydrocarbons and who developed a process for manufacturing high-octane gasoline. While studying in Munich (1897) Ipatieff achieved the synthesis of isoprene, the basic unit of the rubber molecule. Upon return to Russia he worked particularly on the use of high-pressure catalysis and of metallic oxides as catalysts. With these techniques, he helped to establish the petrochemical industry in both pre- and post-revolutionary Russia. Before WW I, he had synthesized isooctane, and had polymerized ethylene. After moving to the U.S. (1930), Ipatieff showed how to convert low-octane gasolines into high-octane by 'cracking' hydrocarbons at high temperatures.
