The first wrench was made by Solymon Merrick in 1835. I can't really tell a biography about him because there is very little information about him. However, I know that Solymon patented the wrench in May.7,1842. It was patent #38. After Solymon invented the wrench, other inventors followed Solymons idea and made similar inventions.Such as the monkey wrench, pipe wrench and the ratchet wrench The first wrench had a S shaped handle and a straight angle. Before it was called a wrench it was called a spanner. The first wrench had a S shaped handles and a straight angle. In the early days, the wrench was made out of wrought iron. Now wrenches are made out of metal People loved how the wrench worked because they liked how that you don't need to use that much power to use the lever.
