1839 – John Herschel takes the first glass plate photograph.
Herschel made numerous important contributions to photography. He made improvements in photographic processes, particularly in inventing the cyanotype process, which became known as blueprints, and variations, such as the chrysotype. In 1839, he made a photograph on glass, which still exists, and experimented with some colour reproduction, noting that rays of different parts of the spectrum tended to impart their own colour to a photographic paper. Herschel made experiments using photosensitive emulsions of vegetable juices, called phytotypes, also known as anthotypes, and published his discoveries in the Philosophical Transactions of the Royal Society of London in 1842. He collaborated in the early 1840s with Henry Collen, portrait painter to Queen Victoria. Herschel originally discovered the platinum process on the basis of the light sensitivity of platinum salts, later developed by William Willis.
Herschel coined the term photography in 1839. Herschel was also the first to apply the terms negative and positive to photography.
Herschel discovered sodium thiosulfate to be a solvent of silver halides in 1819, and informed Talbot and Daguerre of his discovery that this "hyposulphite of soda" ("hypo" ) could be used as a photographic fixer, to "fix" pictures and make them permanent, after experimentally applying it thus in early 1839.
Herschel's ground-breaking research on the subject was read at the Royal Society in London in March 1839 and January 1840.

Jingle bell, jingle bell, jingle bell rock
Jingle bells swing and jingle bells ring
Snowin' and blowin' up bushels of fun
Now the jingle hop has begun
Jingle bell, jingle bell, jingle bell rock
Jingle bells chime in jingle bell time
Dancin' and prancin' in Jingle Bell Square
In the frosty air
What a bright time, it's the right time
To rock the night away
Jingle bell time is a swell time
To go glidin' in a one-horse sleigh
Giddy-up jingle horse, pick up your feet
Jingle around the clock
Mix and a-mingle in the jinglin' feet
That's the jingle bell rock
Jingle bell, jingle bell, jingle bell rock
Jingle bell chime in jingle bell time
Dancin' and prancin' in Jingle Bell Square
In the frosty air
What a bright time, it's the right time
To rock the night away
Jingle bell time is a swell time
To go glidin' in a one-horse sleigh
Giddy-up jingle horse, pick up your feet
Jingle around the clock
Mix and a-mingle in the jinglin' feet
That's the jingle bell
That's the jingle bell
That's the jingle...

It is good, but here is my response
I've finished the first book for Bread of Life compilation for populist podcasters VivaFrei, AUS, The Duran and Bongino.
In the first volume, with quotes from months Jan to Apr, I write about how Australia came to be up to Federation.
In the 2nd volume I write about Australia from Federation to Menzies (Ming the Merciless)
In the third edition I write about Australia post Menzies.
