Let's not get mythological.
The Heyday of Fountain Pens is now.
So, let me show it with some anecdotes.
My great-grand-father was nicknamed "the man who reads". There was a time when "reading" was enough to earn you a distinguishing nickname.
His daughter, born in 1901, my grand-mother, became a midwife in her youth. When I was a kid, I remember this monthly ritual at her house: people would gather to bring the letters from their immigrant sons for her to read and write the answers back. By then, a lot of youths would go elsewhere to work and their main communication form with their families was by letter, which would be sent back (and forth) once each one-three months (I remember 1 was "normal", 3 was considered stretching and people would start worrying). She was one of "the" reference persons in the village/town. So, not everybody did a ) write daily nor b ) have an FP or other writing devices. The most pervasive one was the pencil, used by artisans like my grandfather and carried on the ear.
In the 50's, her brother authored a successful book that became a best-seller and made it into a movie... by typing the memories of illiterate war heroes in an old Underwood typewriter from the early 20th C I would see when staying at his house (and learned to use).
My grandma made it a point that her daughter got an education (a "real" one, not a "ladies" one) and my mother became a primary school teacher. When I was too young (maybe 4) we moved to a capital city, where there was more work (and less migration). That's why I would see those scenes at my grandma's back in the village. Still, when I was in primary school I would often be asked by my father (also a primary school teacher), or my mum, to go back to school at 8pm to remember the other parent to go back home. They alternated in giving reading/writing/4 rules lessons for adults after kids' school. Even as late as through the 70's, there was many illiterate people. I also remember the one-person stands at the entry of public buildings where someone with a typewriter offered typing in documents for people as a way earn his living. Even owning a typewriter could be "distinguishing" before the Xerox machine.
In the very late 60's or very early 70's I was finishing primary school, with a meager "weekly pay" (remember my parents were teachers, and around here the saying was "you're hungrier than a school teacher"), and still one year, I was so proud of them, I decided to save my pay to buy them each a nice pen in sterling silver engraved with their name. Took me almost a year's pay (including birthday, Xmas presents and all), to get the two Sheaffers. So, even a kid could get a good pen -well, yeah, not that swiftly, it's true, and you had to be motivated-.
Fast forward to the early 90's. I was a successful young professional, had my own flat. One day the neighbor downstairs calls to tell me of a water leak. I come down to see it before calling the plumbers and masons in and notice a K1 reading-booklet. I ask her if she had the grand-sons around and she proudly informs me she's learning to read. I tactfully show my interest and she lets me know that her husband had died a month ago (I knew him, but wasn't aware) and she had never had any need or reason to learn reading and writing (or the numbers) because it was her husband that took care of everything. After the decease, she had to fill in all paperwork and needed to learn. I couldn't but express my deepest admiration for her and offer any help I could give.
Mind you, that was the early 90's! Even that late there was still people who were hardly able to write.
Fast forward again, to the 2000's. My mother in law, who certainly knew reading and writing, and even a couple of foreign languages, informs us she's enrolled in the University at 80+. She had finally decided to address her lifelong frustration of not being able to attend University. She would became the oldest person to graduate in the country.
Many forget that women had very few rights and, although there were certainly exceptions, they were so, exceptions. That, even among men, not everybody knew how to read or write. Most women would not get a proper education and aspired to, at most, become secretaries by learning shorthand and typing. A few would (like my parents) volunteer their spare time for free to educate adults, because there was a lot of illiteracy.
The time when everybody writes is now. The time when if anybody makes a new pen, ink or paper anywhere in the World and is instantly known worldwide is now. The time when getting a pen hand-crafted by an expert artisan in the antipodes mailed to your doorstep at a price affordable for most people is now. Even more, the time when writing is easier on a computer is now, and so when you take a pen, you give a special meaning and value beyond plain functionality for communication, to writing, style, calligraphy, color and tools, is now.
The heyday is now.
It is lovely to have fond memories of Ye Olde Times, but let us not paint everything rosy in our memories, for it wasn't.
Plus, wouldn't it be a pity otherwise? What would it say of progress if any past time was better than now? These are rethorical questions, please do not answer, because that would enter the realm of politics, but, if you have a few minutes, try to think of them.
