He was a mathematician, physicist, astronomer, theologian, and author.
However, his most prominent failure was losing an entire fortune in the first stock market bubble in history, the South Sea Company in 1720.

Before 1720 most of his investments were in safe and reliable securities, various government bonds that delivered a regular stream of income, and shares in a few of the larger companies on the exchange, including South Sea Co.
Government bondholders were given the option to exchange their securities into South Sea Co. shares.

However, the potential for dividend increases and sizable capital gains was created when Parliament gave the company a monopoly on trade with Spain’s colonies in South America.

It required all companies that sold stock to the public to hold a royal charter aiming to control rampant speculation.
A well-bribed Parliament and ruling ministry accepted the idea in February, and the deal became official in April.


Over the next eight years, he picked up more shares, using his savings and the proceeds from selling his shares in other companies.
In 1720, he converted his government bonds and annuities into the stock.

At this point, Newton unloaded most of his shares for a profit of more than £20,000 equal to 200 years of his former annual salary as a professor at the University of Cambridge.

This was amplified by the hundreds of newspapers in London posting glowing articles from esteemed authors, along with rumors about South American commodities that would be imported back to Europe.

The stock was also made easier to buy through installment plans with 10% downpayments.
With England in a euphoric mood, watching from the sidelines was hard to do.
By mid-June, Newton could no longer stand the thought of the money he’d “lost” by selling too soon and began to buy back in.
By mid-August, he was paying £700 to £1,000 a share, more than double the price he’d sold in April.
In the summer, news broke that insiders were selling.
The stock began to tumble and within a few weeks, plunged back to the £200 level.
So ended the infamous South Sea Bubble.

Newton’s losses were catastrophic, likely £20,000, the equivalent of $4 million today.
1720 was sometimes referred to as the “Bubble Year”

He allegedly forbade everyone from uttering the words "South Sea" in his presence.

Imagine for a moment the most obscurantist, jargon-filled, po-mo article the politically correct academy might produce. Pure SJW nonsense. Got it? Chances are you're imagining something like the infamous "Feminist Glaciology" article from a few years back.https://t.co/NRaWNREBvR pic.twitter.com/qtSFBYY80S

The article is, at heart, deeply weird, even essentialist. Here, for example, is the claim that proposing climate engineering is a "man" thing. Also a "man" thing: attempting to get distance from a topic, approaching it in a disinterested fashion.

Also a "man" thing—physical courage. (I guess, not quite: physical courage "co-constitutes" masculinist glaciology along with nationalism and colonialism.)

There's criticism of a New York Times article that talks about glaciology adventures, which makes a similar point.

At the heart of this chunk is the claim that glaciology excludes women because of a narrative of scientific objectivity and physical adventure. This is a strong claim! It's not enough to say, hey, sure, sounds good. Is it true?
