Theodore Alteneder
Theodore Alteneder started producing drawing instruments in 1850. According to one website, "he patented an improved joint design in 1850 and in 1871 he was granted a second patent for further improvements "which made (the joint) dust-proof and free from wear and friction". Alteneder was awarded a medal for his designs in the Centennial Exhibitions of 1876 and a silver medal was received from the Franklin Institute in 1885. Theodore Alteneder was one of few American manufacturers of drawing instruments. He continued manufacturing as late as 1912."
