Oh, I'm always so pleased when that happens. Another successfully completed project and the joy of a job well done. I know it's not solely my merit, but without me it wouldn't be so easy. A hundred years ago, for example, there was only the fountain pen, which was undoubtedly elegant, but all that filling it up, and smudging... Before that, you had to dip a quill in ink. Can you imagine that? Dip, apply, apply, apply, not dry, wait, apply, smear, wait, apply, apply and so on ad infinitum. Well, I put an end to that, me, the ballpoint pen. Of course, many people tried to invent a writing instrument that worked simply and reliably, but not only did they lack ideas, but also the technical background. In the end, a Hungarian journalist-turned-inventor, László Bíró, solved the problem, and in 1943 he registered his patent in Argentina. How did he make his invention a success? By changing two important elements. On the one hand, he made the ball in me more precise. By the way, this has been improved over time, nowadays it also has small holes, so it can hold more ink and spread it on the paper even more evenly. The other problem was the ink itself, because the ones used at the time smeared and did not dry well. This was finally replaced by Bíró who used a fast-drying printer’s dye. I became successful very quickly, but Bíró's business in Argentina did not go well, so he sold the patent rights to a French businessman named Marcel Bich for a million dollars. This was good money at the time, but compared to the fact that Bich's company still operates today and has sold millions of ballpoint pens, it is nothing. Although personally, I'm not complaining because, for example, I was employed by the American and British air forces because I can be reliably used on airplanes at altitude, so much so that I have already been into space. My operation is not affected by gravity. Nor has the world forgotten László Bíró. Argentina celebrates Inventors' Day on his birthday, and the ballpoint pen is still called a ‘biro’ in many languages.
