I can't post a link to the email I received. However, it references a youtube video on the topic. The video is by Derek Muller.

It was an ingenious solution, but the skills required could have been learned in a shop class and would never be taught in a university

Exactly.

Book smart don't usually cut it in the real world. And I'm book smart.

In college I painted some fluorescent tube blue and used them to light up my dorm room...didn’t need a PHD for that.

Years ago, my boss got his PhD by making one of the blue LEDs that had the right color, but too little power (as mentioned in the excellent video). At that time, successful production of the led as covered in the video was years away.

The video is great, and should serve as a reminder to all that perseverance is the prime ingredient to success.

Which came first?

The Blue LED, or the white LED?

(Hint: The Blue LED.... White LEDs are Blue LEDs shining through a Cerium Yttrium Garnet phosphor)

Excellent video. Thanks.

There’s a YouTube video that details the travails and successes of the Japanese genius who created the first useful blue LED. Good News: It’s a great and inspiring story and despite little support he succeeded and got a Nobel prize for his efforts. Bad News: Fully animated billboards.

Outstanding video!

I remember when the 1st blue LEDs from Nichia came out and seeing one at the Consumer Electronics Show. My reaction was “ohhhhh..... shiiiittt!” (In a good way!)

That Channel, Veritasium, has a great piece on German scientist, Fritz Haber:
