"They all laughed at Christopher Columbus when he said the world was round"

Nah, they laughed because they already knew the world was round–and his math about earth's size was incorrect.

This is a #ColumbusDay thread about how so much of what we were taught about him was wrong:

#BlackHistoryMonth In the Navy, I was fortunate to serve at Commander Cruiser Destroyer Group 2(CCDG2). I reported to duty in 1981 as Radioman Seaman Apprentice(RMSA), and served through 1985 in the communications division achieving the rank of Petty Officer 2nd Class(RM2/SW) /1

This was my first duty assignment. But my first is not important as the first African-American who served as CCDG2's Commanding Officer prior to my arrival, Rear Admiral Samuel L. Gravely, Jr. He was a trailblazer. He was commissioned an Ensign on November 14, 1944. /2

He enlisted and then became one of the first commissioned African-American officers in the US Navy. He was denied housing and even jailed for impersonating an officer. He withstood a cavalcade of abuse and racism and still managed to rise through the ranks of the Navy. /3

He became the first to serve under combat conditions during WW2. He served during the Korean & Vietnam War. He was the first to command a fighting vessel, and commander of the 3rd fleet. He served as Communications officer on the USS IOWA BB-61 /4

He served as the first African-American to command (USS Theodore E. Chandler (DD 717)); command a major warship (USS Jouett (DLG 29)) - and was the first African-American to achieve the rank of Captain in 1967. /5

In 1637, the Dutch Republic erupted into a speculative fever over an unlikely item...the tulip.

Tulip Mania has become a legend synonymous with market euphoria and bubbles. But is this tale all it's cracked up to be?

Who's up for a story?

👇👇👇

1/ The tulip is a spring-blooming flower native to the valleys of the Tien Shan Mountains in Central Asia.

It is believed to have been introduced to Europe in 1554, when an ambassador of the Holy Roman Emperor sent tulip bulbs and seeds to Vienna from the Ottoman Empire.

2/ Tulips gained in popularity as people were attracted to their rich color and ability to grow in sub-optimal conditions.

They soon became a coveted status symbol for the wealthy.

The Semper Augustus, with its colorful, flame-like streaks, was the most desired of them all.

3/ By the early 1600s, the Dutch Republic was entering a golden age.

Many financial innovations popped up during this time - the first stock exchange, for example.

But it was another financial innovation that would propel tulips into historical lore: the futures contract.

4/ As tulips grow slowly and may take several years to bloom, paper contracts were written that entitled the buyer to the future tulips.

These contracts were freely-traded.

So in addition to the physical market for tulip bulbs, a thriving paper market was established.

The Story of how Mary Slessor Stopped the killing of Twins but sadly died of Fever.

All you need to know

Retweet to educate someone

Killing new-born twins was common practice in the 19th century among the Ibibio people of Nigeria, but one Scotswoman went to great lengths to put an end to this.

Aberdeen-born Mary Slessor was one of the few missionaries in Africa who learnt the local language, adapted to the native customs and environment and gained the trust of the locals in order to make a truly positive impact.

Her father, a shoe-maker from Buchan, became incapacitated by alcoholism and Mary more or less became the breadwinner for the family.

From the age of 11, she worked as a ‘half-timer’ mill girl in the Baxter Brothers and Co Ltd, spending half the day at a school provided by the mill owners and the other half working for the company

This is the field where my grandmother’s family was murdered in April 1943. I met one of the witnesses, a neighbor, several years ago. She said she saw them being marched away, was told by a Nazi to get back inside or risk joining them... 1/#InternationalHolocaustRemembranceDay

My grandmother and her kid sister ran for their lives into the woods. One detail that sticks out from my great aunt’s testimony many yrs later: the sunflower stalks in Grodzisko were so tall you could lay down and hide among them. Presuming the Nazis didn’t bring the dogs. 2/

My grandmother paid a farmer to hide them in the attic of his barn. This was a perilous act. After the war, my grandmother would send the farmer care packages until he died, as a token of her gratitude.

Most of my grandmother’s family were killed in those awful days in 1943.

In testimony my great aunt recorded—amazing to listen to, truly—she remembers being perpetually hungry and freezing. She recalls seeing a cherry tree outside the window of the attic and fainting. She also remembers my her sister’s nightmares, the screams for Eli...

Before they ran for their lives, my grandmother had given away her 3yo son Eli for safekeeping while she hid. After the war, she returned for him, but he was gone. Vanished. No one could say what happened to him.

I have been searching for Eli, my uncle, for two decades.
