Demonstrably, one thing about the life of the electrical engineer Mark Anthony remains in historical memory. His dates of birth and death don’t seem to be accessible online, but during the years of his floruit, 1909-1911, he is known to history to have been experimenting in New York with what we would now call a radio-controlled drone bomber. About that the online record yields two reprinted newspaper articles. Says Anthony in one of them, from 1909,

There are also two 1909 portraits in the Library of Congress’s George Grantham Bain Collection, an archive of news agency photographs. One is captioned “Anthony at transformer,” and it shows a standing man, presumably Anthony, looking down at a table upon which rests a transformer. By analogy with “at bat” or “at the wheel,” the phrase “at transformer” is a dramatis persona in a scene of power and mastery.
The other portrait . . .
Dark but with a rubbery sheen, the rope-bound object in the background may be what the newspaper article calls “a balloon 22 feet long, with a capacity of 600 cubic feet of gas.” Anthony’s right hand rests on what looks like a compressed-gas cylinder’s hose connection, and it seems to be holding the inflation tube of another balloon, tied off with string. The system looks ready for arming and flight, and the artist who memorialized the event for history bent his name to the masterful arc of the inventor’s shoulder.
A later article about radio control extinguishes the expectation. From Germany in 1911, it reports: “A somewhat similar invention was recently reported from New York, where Mark Anthony, a well-known electrical engineer, offered his device to the United States Government for $125,000. The offer was declined. . . ” But in what Cavafy might have called the days of 1909, an image inflated itself with curves bulging into more curves and then went tense and still, in a waiting phase, at the brink of a moment when the curves might merge, then soar free enclosed in straining rubber, then explode and cause to explode. The balloon, the hat, the nose, and the double beacon of the eyes behind their collimators: all these awaited the unbuttoning of what a poem written in 1911 was to call “My morning coat, my collar mounting firmly to the chin, / My necktie rich and modest, but asserted by a simple pin.”
The unbuttoning didn’t take place in 1909, but the readiness was all. In 1912 Vaslav Nijinsky would fuck the nymph’s veil. Two years after that, the term “blow sky-high” would explode into aeronautical meaning.

Title: Joseph Conrad, The Secret Agent, chapter 4: “I have the means to make myself deadly, but that by itself, you understand, is absolutely nothing in the way of protection. What is effective is the belief those people have in my will to use the means. That’s their impression. It is absolute. Therefore I am deadly.” “Those people” are the police; “the means” is a bomb in the speaker’s breast pocket, with its detonator button in his hand. I visualize a hand looking like Mark Anthony’s.
