I am glad you like it. Too bad virtually everyone forgot about this anniversary. Well, next year's the first century of diode history, maybe then it will be a more popular topic.
On November 16, 1904, former Edison employee John Ambrose Fleming patented first thermionic (vacuum-tube) diode in Britain. The US patent for the same invention was granted the following year. Today, these diodes are used in some high-power applications, audiophile devices, and musical instruments.
