The exceptional life of Benjamin Banneker - Rose-Margaret Ekeng-Itua
-
0:08 - 0:11Sometime in the early 1750s,
-
0:11 - 0:14a 22-year-old man named
Benjamin Banneker -
0:14 - 0:18sat industriously carving cogs
and gears out of wood. -
0:18 - 0:20He pieced the parts together
-
0:20 - 0:23to create the complex inner working
of a striking clock -
0:23 - 0:26that would, hopefully,
chime every hour. -
0:26 - 0:30All he had to help him was
a pocket watch for inspiration -
0:30 - 0:32and his own calculations.
-
0:32 - 0:35And yet, his careful engineering worked.
-
0:35 - 0:39Striking clocks had already been
around for hundreds of years, -
0:39 - 0:43but Banneker's may have been
the first created in America, -
0:43 - 0:47and it drew fascinated visitors from
across the country. -
0:47 - 0:48In a show of his brilliance,
-
0:48 - 0:53the clock continued to chime
for the rest of Banneker's life. -
0:53 - 0:57Born in 1731 to freed slaves
on a farm in Baltimore, Maryland, -
0:57 - 0:59from his earliest days,
-
0:59 - 1:02the young Banneker was obsessed
with math and science. -
1:02 - 1:06And his appetite for knowledge only grew
as he taught himself astronomy, -
1:06 - 1:08mathematics,
-
1:08 - 1:09engineering,
-
1:09 - 1:12and the study of the natural world.
-
1:12 - 1:15As an adult, he used astronomy
to accurately predict -
1:15 - 1:17lunar and solar events,
-
1:17 - 1:20like the solar eclipse of 1789,
-
1:20 - 1:24and even applied his mathematical skills
to land use planning. -
1:24 - 1:29These talents caught the eye of a local
Baltimore businessman, Andrew Ellicott, -
1:29 - 1:33who was also the Surveyor General
of the United States. -
1:33 - 1:36Recognizing Banneker's skills in 1791,
-
1:36 - 1:40Ellicott appointed him as an assistant
to work on a prestigious new project, -
1:40 - 1:43planning the layout
of the nation's capitol. -
1:43 - 1:47Meanwhile, Banneker turned
his brilliant mind to farming. -
1:47 - 1:51He used his scientific expertise
to pioneer new agricultural methods -
1:51 - 1:54on his family's tobacco farm.
-
1:54 - 1:56His fascination with the natural world
-
1:56 - 2:01also led to a study on the plague
life cycle of locusts. -
2:01 - 2:05Then in 1792, Banneker
began publishing almanacs. -
2:05 - 2:10These provided detailed annual information
on moon and sun cycles, -
2:10 - 2:11weather forecasts,
-
2:11 - 2:15and planting and tidal time tables.
-
2:15 - 2:17Banneker sent a handwritten copy
of his first almanac -
2:17 - 2:21to Virginia's Secretary of State
Thomas Jefferson. -
2:21 - 2:24This was a decade before Jefferson
became president. -
2:24 - 2:27Banneker included a letter imploring
Jefferson to -
2:27 - 2:30"embrace every opportunity to eradicate
-
2:30 - 2:33that train of absurd
and false ideas and opinions" -
2:33 - 2:36that caused prejudice
against black people. -
2:36 - 2:40Jefferson read the almanac and wrote
back in praise of Banneker's work. -
2:40 - 2:43Banneker's correspondence with
the future president -
2:43 - 2:46is now considered to be one of the first
documented examples -
2:46 - 2:49of a civil rights
protest letter in America. -
2:49 - 2:52For the rest of his life,
he fought for this cause, -
2:52 - 2:56sharing his opposition to slavery
through his writing. -
2:56 - 2:59In 1806 at the age of 75,
-
2:59 - 3:03Banneker died after a lifetime
of study and activism. -
3:03 - 3:06On the day of his funeral,
his house mysteriously burned down, -
3:06 - 3:08and the majority of his life's work,
-
3:08 - 3:11including his striking clock,
was destroyed. -
3:11 - 3:14But still, his legacy lives on.
