Sometime in the early 1750s,

00:10
a 22-year-old man named Benjamin Banneker
1
10652
3320
00:13
sat industriously carving cogs and gears out of wood.
2
13972
3849
00:17
He pieced the parts together
3
17821
2231
00:20
to create the complex inner working of a striking clock
4
20052
2640
00:22
that would, hopefully, chime every hour.
5
22692
3387
00:26
All he had to help him was a pocket watch for inspiration
6
26079
3724
00:29
and his own calculations.
7
29803
2304
00:32
And yet, his careful engineering worked.
8
32107
2722
00:34
Striking clocks had already been around for hundreds of years,
9
34829
3961
00:38
but Banneker's may have been the first created in America,
10
38790
4108
00:42
and it drew fascinated visitors from across the country.
11
42898
3705
00:46
In a show of his brilliance,
12
46603
1503
00:48
the clock continued to chime for the rest of Banneker's life.
13

Born in 1731 to freed slaves on a farm in Baltimore, Maryland,
14
53172
4051
00:57
from his earliest days,
15
57223
1410
00:58
the young Banneker was obsessed with math and science.
16
58633
3189
01:01
And his appetite for knowledge only grew as he taught himself astronomy,
17
61822
4670
01:06
mathematics,
18
66492
1360
01:07
engineering,
19
67852
1080
01:08
and the study of the natural world.
20
68932
2691
01:11
As an adult, he used astronomy to accurately predict
21
71623
2991
01:14
lunar and solar events,
22
74614
2190
01:16
like the solar eclipse of 1789,
23
76804
2950
01:19
and even applied his mathematical skills to land use planning.
24
79754
4590
01:24
These talents caught the eye of a local Baltimore businessman, Andrew Ellicott,
25
84344
4250
01:28
who was also the Surveyor General of the United States.
26
88594
4040
01:32
Recognizing Banneker's skills in 1791,
27
92634
3190
01:35
Ellicott appointed him as an assistant to work on a prestigious new project,
28
95824
4110
01:39
planning the layout of the nation's capitol.
29
99934
3310
01:43
Meanwhile, Banneker turned his brilliant mind to farming.
30
103244
3861
01:47
He used his scientific expertise to pioneer new agricultural methods
31
107105
4362
01:51
on his family's tobacco farm.
32
111467
2659
01:54
His fascination with the natural world
33
114126
1979
01:56
also led to a study on the plague life cycle of locusts.
34
116105
4841
02:00
Then in 1792, Banneker began publishing almanacs.
35
120946
4369
02:05
These provided detailed annual information on moon and sun cycles,
36
125315
4671
02:09
weather forecasts,
37
129986
1309
02:11
and planting and tidal time tables.
38
131295
3301
02:14
Banneker sent a handwritten copy of his first almanac
39
134596
2778
02:17
to Virginia's Secretary of State Thomas Jefferson.
40
137374
3614
02:20
This was a decade before Jefferson became president.
41
140988
3347
02:24
Banneker included a letter imploring Jefferson to
42
144335
2871
02:27
"embrace every opportunity to eradicate
43
147206
2742
02:29
that train of absurd and false ideas and opinions"
44
149948
3119
02:33
that caused prejudice against black people.
45
153067
3099
02:36
Jefferson read the almanac and wrote back in praise of Banneker's work.
46
156166
4140
02:40
Banneker's correspondence with the future president
47
160306
2550
02:42
is now considered to be one of the first documented examples
48
162856
3120
02:45
of a civil rights protest letter in America.
49
165976
3180
02:49
For the rest of his life, he fought for this cause,
50
169156
2550
02:51
sharing his opposition to slavery through his writing.
51
171706
4431
02:56
In 1806 at the age of 75,
52
176137
2502
02:58
Banneker died after a lifetime of study and activism.
53
178639
3928
03:02
On the day of his funeral, his house mysteriously burned down,
54
182567
3331
03:05
and the majority of his life's work,
55
185898
1940
03:07
including his striking clock, was destroyed.
56
187838
3489
03:11
But still, his legacy lives on.
