This document summarizes innovations and innovators from Africa. It discusses ancient African innovations in construction engineering like the pyramids, which were built without modern machinery over 20 years. It also mentions early developments in writing with Egyptian hieroglyphics as the first known alphabet over 3200 years ago. In medicine, it notes that many modern medical treatments were first used in Africa centuries ago, including surgery, vaccination, and dental work. The document then profiles several African innovators, including Dr. Bennet Omalu who discovered Chronic Traumatic Encephalopathy, Dr. Soni Oyekan with 14 patents in oil refining, and Dr. Thomas Mensah's work in nanotechnology and fiber optics.

2. • Africa is the seat of civilization
• Life started from Africa before we all migrated to
different continents.
• But not so much is known about Africa.

(INNOVATIONS)

4. CONSTRUCTION ENGINEERING
= *48.8
146m in height
7 storeys building
at NUT with a
height of 24m

5. How was it built?
• No Construction
Machines.
• No Engineering
Mathematics
• No concrete
• Built totally for over
20 years by
Manpower
Scientists still don’t
know how the
pyramids were built

6. THE ART OF WRITING
The first known
alphabets are Egyptian
hieroglyphics.
They were developed
in 32nd century, over
3200 years ago.

7. My name in
Egyptian
hieroglyphics

8. Medicine
• Many treatments used today in
modern medicine were first
employed in Africa centuries ago.
• The earliest known surgery was
performed in Egypt around 2750
B.C.
• Medical procedures performed in
ancient Africa include vaccination,
autopsy, limb traction and broken
bone setting, bullet removal, brain
surgery, skin grafting, filling of
dental cavities, installation of false
teeth.
