Looking Heavenward

The temporary Sunday School teacher was struggling to open a combination lock on the supply cabinet. She had been told the combination, but couldn't quite remember it. She went to the pastor's study and asked for help. The pastor came into the room and began to turn the dial. After the first two numbers he paused and stared blankly for a moment.Finally he looked serenely heavenward and his lips moved silently. Then he looked back at the lock, and quickly turned to the final number, and opened the lock. The teacher was amazed. "I'm in awe at your faith, pastor," she said. "It's really nothing," he answered. "The number is on a piece of tape on the ceiling."

Siegfried Marcus

Born 18 Sep 1831; died 30 Jun 1898 at age 66.German-Austrian inventor who built four of the world's earliest gasoline-powered automobiles. Marcus held about 76 patents (though none on his automobiles) in about a dozen countries, including an electric lamp (1877), various other electrical devices, a carburetor and an igniter for explosives. He installed the first electric bell in the bedroom of Empress Elisabeth, and he became an instructor in physics to the ill-fated Crown Prince Rudolf. He built and marketed internal combustion engines. Marcus first started working on a self-propelled vehicle about 1860, making significant contributions in the course of further development. Photographs of his first car, built about 1864, were taken in 1870. The second car - the landmark - was built about 1875 in his Vienna factory. It was first equipped with a two-cycle engine, and later, a four-cycle engine.
