Here are some one liners...
Paris in the Spring and Guillotines -- Dr. Guillotin suggests a killing machine for capital punishment as a mercy. It is eventually named after him. It is used for the first time this year. The crowd is disappointed.
The New York Stock Exchange and the US Mint are Established -- I talk about the history of the NYSE and how difficult it is to create a good exchange in metals between silver and copper.
Let There be Light, Heat and High Speed Communication -- Gas lighting, blast furnaces and semaphore towers.
Paris in the Spring and GuillotinesAnd so the beheadings begin with new death penalty legislation in France. Capital punishment should be more merciful. (In these days "the rack" is considered fairly reasonable for the traditional law-and-order guys but we are talking more merciful than that.) Dr. Guillotin has suggested a killing machine... a frame holding a weighted blade which drops. The head is sliced off at the neck in one stroke. Done. It is to be applied equally to aristocrat and commoner alike. It is first used on a highway robber. The details are unclear, but apparently he killed someone during a robbery. On April 25th at 3:30 in the afternoon, Nicolas Pelletier, climbs up to the machine. He is wearing a red shirt, and the execution device is painted red. A large crowd awaits the event. In less than a minute the deed is done. The crowd is disappointed. They had hoped it would last longer. At least with a hanging the guy kicks a little. But it is the law and it will remain the only form of capital punishment in France until 1981 with the exception of military punishment where a firing squad might be more practical.     
The New York Stock Exchange and the US Mint are EstablishedIn 1792 if you want to find a stock broker, what do you do? You look for a coffee house. (And if you want to find your Congressman you go to the local tavern. It doesn't have to be pretty. It just has to work.) Currently, the stock brokers have outgrown the old coffee house and they want to buy their own place. So they meet under the buttonwood tree at 68 Wall Street and sign an agreement to open the Tontine Coffee House. (A "tontine' is a type of investment plan.) The agreement they sign is called the Buttonwood Agreement, after the tree. They don't know where this is going, but they start off trading in stock for the First Bank of the United States... an early version of the Federal Reserve. Over the years the Stock Exchange will move several times, sometimes renting, and one time settling into a building until a fire guts the place. In 1817 they will call themselves the 'New York Stock and Exchange Board'. Much later they will shorten it to the New York Stock Exchange. By 1865, they will move into the first of 3 buildings at the site which constitutes their modern location at Wall Street and Broad.     
Let There be Light, Heat and High Speed Communication
- William Murdoch applies gas lighting to his own home. He is using coal-gas (later called town gas) which is a by-product of the coking process. By the 1850s, town gas will be used for cooking and heating too. It will be supplemented with natural gas in the 1890s. Town gas will be replaced by natural gas by the 1960s.    
- Semaphore towers allow high speed communication over long distances in France. (These semaphores have large arms with paddles, and they are mechanically manipulated.) Relay stations are set up for longer distances. In less than 20 years the heliograph will be invented (using the sun and mirrors) and the electrical telegraph. We are on our way!
