...office in the Old Arcade Bldg., Cleveland, reporters listened to the low, kindly voice of a long-beloved citizen-Charles Francis Brush, 79, six feet tall, big of frame, bushy of eyebrows, world-famed physicist, inventor of the arc light. He answered questions concerning the $500,000 foundation he had just endowed...
...farm he had tinkered with wires and electrical apparatus. At 27, he had designed the first open coil dynamo, following this with an arc lamp, the "ring clutch," in which the carbon is clutched by a ring attached to an armature which automatically keeps the light steady. This not only solved a long standing difficulty but brought the price to street level. Three years later (1879) the Public Square in Cleveland glowed under the first public arc lights...
Only in 1873, at Vienna, was it discovered that one electric dynamo could make another rotate. The second became a motor, and the electric transmission of power came within the possibilities of engineering. A Russian, Paul Jablochkov, invented the arc light in 1876; Thomas Edison the incandescent light in 1879. In 1881 Thomas Edison opened the first public electric supply station. And only five years later Tokyo, for more than two centuries secluded from European and U. S. science, also had its electric light system. The Tokyo Electric Light Co. was the innovation. It first served current for 75 lamps...
Although many spikes and cleats have done their obliterative best, the Stadium has not quite lost the touch of a buskined foot. The Joan of Arc of Maude Adams was one of the first plays to be presented here, and "Caliban", the effort of Percy Mackaye to go Browning, and Shakespeare, one better was given shortly after the World War. And the classical play has not absented itself from classical setting, for the "Iphigenia in Taurus" of the company of Granville Barker likewise saw worthy performance in appropriate surroundings. Within the year Miss Anglin's "Electra" has been produced...
Skyrockets were familiar things to Herr von Opel's audience. You light the fuse, the powder burns, the gases expand so rapidly that they push the rocket up through the air in a screeching arc. But could an automobile be substituted for the stock of a skyrocket and pushed along the ground by posterior expansion? Herr von Opel would show them...
