The four inventions I learned about this week were the Portland Cement, the Electromagnets, the Passenger Rail, and lastly the Matches.

Joseph Aspdin made Portland cement and patented it. Joseph’s son, William, made his own one which is the real formula, but he did not patent it. William Sturgeon invented the electromagnet around 1800 after Oersted discovered electricity’s and magnetism’s link together. George Stephenson invented the one and only passenger rail after spending a living developing railroad lines. His invention provides a fast mode of transportation. John Walker invented matches by accident in 1826. Many improvements were made like the matchbook in 1890. The improvements did not have a patent.
