When you are old and grey and full of sleep,
And nodding by the fire, take down this book,
And slowly read, and dream of the soft look
Your eyes had once, and of their shadows deep;
 
How many loved your moments of glad grace,
And loved your beauty with love false or true,

And loved the sorrows of your changing face;
 
And bending down beside the glowing bars,
Murmur, a little sadly, how Love fled
And paced upon the mountains overhead
And hid his face amid a crowd of stars.—William Butler Yeats, “When You Are Old”

William Butler Yeats (above) was born on his date in 1865.

Armstrong, building on 15 years of research into high frequency signals, had devices that could send and receive high frequency signals. Armstrong played a jazz record through AM equipment and then through FM. A reporter who was there wrote, “If the audience of 500 engineers had shut their eyes they would have believed the jazz band was in the same room. There were no extraneous sounds.” It worked, yet the FM radio era lay decades off in the future.
