In 1705, joseph aspdin was a prisoner in Boston. He had been convicted of manslaughter, and was serving his sentence in the common prison. There he met a fellow prisoner, who had been imprisoned for being an accessory to a murder he didn’t commit. The man told him about his work as a tinsmith: how he made things that only novices can make, like “monkey-nuts” and “spital-cauls.”

Aspdin knew about the English practice of patenting inventions for twenty years or so after they were invented. He realized that if he could get the patent for his invention from the king (a rare honor) then he could make some money by charging people to make things with it.

So he set out to invent something that would be an improvement on what tinsmiths are used to doing. And in 1709, joseph aspdin patented Portland Cement as an improvement on mortar. It is still one of the most important substances ever invented by human beings.

Joseph Aspinall was a carpenter, and he was also responsible for inventing Portland cement. There was no Portland cement in England until Aspinall invented it in 1824. He won a patent for his invention in 1824, but it took another twenty years to sell the patent rights to anyone. The first company that bought the patent was Henry Bessemer, who had already opened a factory and made some money on it by making iron and steel. Aspinall got just 4 pence per ton of Portland cement he had turned out by 1842. The first big break came when George Stephenson started using Portland cement in the infamous Rocket trains of the 1840s.

You may not have known that joseph aspdin’s real name was Joseph Aspinall. It’s an interesting story how he ended up with a name you might recognize from your high school chemistry class: originally, he’d been called Portland Cement because the material didn’t exist at all until he invented it; then he’d been called Cement because that was what his raw material was called (it wasn’t really cement); then he’d become known as Stonewell Cement because his product was used to make large stone walls, like those he built; then finally Asp

But joseph aspdin wasn’t a man. He was a plan for a machine that made cement.

We have to remember that the world is full of things that are not people, but machines. Machines can do things people can’t; you don’t need to invent them yourself. People once had machines inside them, like heart valves, and they still do: they are called batteries. But an important part of your job is to make sure you don’t make mistakes with these machines, or at least that no one else does. And if you do get it right, then other people will want to use the same kinds of machines you invented.

Aspdin’s plan was a kind of cement mixer: it turned sand into concrete by mixing water and sand together in such a way that the water poured out of the bottom and the sand came out of the top. It worked better than any previous cement mixer, but it was still not perfect: it produced concrete that hardened too quickly, so it cracked when people walked on it. It also produced concrete that hardened too slowly, which meant that the first rainstorms would wash away all the work done. So Aspdin decided to add more chemicals to make the concrete harden more slowly, but he didn

Aspdin was the first true cement manufacturer. He gave up his patent in 1815, when he started selling the product under the name Portland Cement. But that doesn’t mean he invented it. Like many other early cement manufacturers, Aspdin’s cement was a mixture of clinker and shale.

By 1815, France was doing more than half of its cement-making in England and Belgium. The French clinkers came from quarries in the north and east of France, where a lot of naturally occurring limestone existed. Aspdin didn’t have to invent the process for making Portland Cement. All he had to do was figure out how to make the mixture work better.

And that, he did: with modern ingredients like fly ash and slag–and, most importantly, with modern methods like grinding rather than crushing clinkers into dust.

Joseph Aspdin, the 17th century British chemist credited with discovering the process of making Portland cement, is buried in an unmarked grave in a churchyard near his birthplace.

Although he was born in 1702, few historians know much about him. The first biography of Aspdin came out in 1827, but the book was immediately forgotten. The first significant new biography appeared in 1972; it was written by a chemistry teacher at the University of New South Wales and not published until after his death.

The book caused a sensation among chemists. It is filled with misinformation and factual errors, but it has done its job: today Aspdin’s name is as familiar to chemists as that of Lavoisier or Priestley.

Aspdin is best known for inventing Portland cement, a widely used building material. He was born in 1728 and died in 1809. He was an engineer and metallurgist who worked for the British East India Company. In 1775 he patented a new kind of cement, which he called “Portland cement.” The English word “cement” was derived from his name. He failed to interest the public in his cement; it didn’t catch on until well after his death.

The name of his patent was “Method of Working Cement.” It wasn’t until 1807 that he came up with the idea of mixing cement with sand. Until then, Portland cement had always been made with chalk or clay as the main ingredient.

Aspdin also invented high-quality white lead paint.

If you have a job, and you’re not sure how to do it and you want to be able to get a better one, there are two common strategies. One is to learn the job, figure out how to do it well, and then apply for the better job. The other is to make up your own job. The second strategy is the sort of thing that has been called creative destruction.

The job market is divided into two kinds: suckers and sharks. Unless you are pretty good at sucking people in, most jobs are for suckers. Most people who get good jobs are not so much smarter than other people as they are luckier; they got the wrong job at the wrong time or were born with the right parents or whatever.

Aspdin was lucky in his own way. He got his patent by being a sucker, not a shark. His invention was Portland Cement, which made him very rich indeed but never changed the world much.
