What will you think when you hear the name “Macintosh”? A computer? Alright, however, far away before the Macintosh computer is invented, the world was rocked with another Macintosh. This was Macintosh coat, which was invented by Charles Macintosh from Scotland. Following his passion in chemistry, Macintosh left his job as a clerk in Glasgow merchant. During his daily experiment, he thought about his clothes. He wondered about a waterproof clothes. Then, he made a new fabric by inserting liquid rubber between two layer of fabric. It probably smell, stiff, and have a risk to melt in hot weather, but it works as a coat. Some years later, by the invention of vulcanising rubber, the Macintosh coat was refined. Then, over years ago, the ‘k’ letter was inserted in Macintosh, so it became the Mackintosh. Now, when we look at the Mackintosh coat, we probably thinks it just a fashion. However, when Charles Macintosh got this idea, it was the real technology. Thank you Mr. Macintosh for protect us from cool and wet!
