3. Aim
• To understand how key events and individuals in design and
technology have helped shape the world.

4. Starter Activity
How many designers or inventors can you name?
What did they each create?

5. The Wright Brothers
The Wright brothers, also known as Orville and Wilbur Wright,
were American siblings and great technological innovators.
They are credited with inventing the
airplane having made the first successful
human flight with a craft powered
by engine.
To help design the wings for planes,
they studied how birds flew
and used their wings.

6. Ada Lovelace
Ada Lovelace, or in full Augusta Ada King The Countess of
Lovelace, was born 10th December 1815 in London, England
and died 27th November 1852.
Lovelace worked closely with Charles Babbage; Babbage
invented the first prototype of the digital computer
we know today, known as the Analytical Engine.
Lovelace was able to create the first program
which would compute Bernoulli numbers
(a sequence of numbers) into instructions.
Lovelace is known to be one of the first computer
programmers.

7. Alexander Graham Bell
Alexander Graham Bell was interested in the
idea of transmitting speech from one place
to another.
Watch this video to find out more about him
and his marvellous invention:

8. Henrietta Vansittart
Henrietta Vansittart was born 1833 in Surry, England
(exact date unknown) and died 8th February 1883.
Vansittart was an inventor, remembered for
creating an innovative design of a propeller.
Vansittart worked closely with her father to
improve the screw propeller which had been
fixed to many British warships.
She was able to improve the propeller,
allowing ships to move faster and
smoother while using less fuel.
She named this propeller the
Lowe-Vansittart propeller.

9. Stephanie Kwolek
Stephanie Kwolek was an American-Polish chemist who worked with
synthetic (humanly-constructed) fibres.
She invented Kevlar, an incredibly light but very strong material.
Kevlar is most commonly known for its use in
bulletproof vests, which have saved thousands of lives.
However, it is also used for
everything from bicycle tires to
boat sails!

10. Maria Beasley
Maria Beasley was born 1847 and died 1904 (exact dates unknown).
Her first invention was for a barrel-hooping machine that would
help speed up the manufacture of barrels. This invention could
make 1500 barrels a day. Beasley had other inventions
alongside this barrel-hooping machine, such as cooking pans,
anti-derailment devices for trains and foot warmers.
Her most well-known invention was her improved
life raft design in 1880. Beasley was able to design
a life raft that was fireproof, safe, compact and
easy to launch. It even had protective railings.
It was Beasley’s life rafts that were on board
one of the most infamous ships, The Titanic.
Maria’s rafts were used to help keep 706 men,
women and children safe until help arrived.

11. Ruth Handler
Ruth Handler designed the Barbie doll, a popular
toy all over the world.
While watching her daughter play with paper
dolls, she set out to invent a 3D doll that children
could play with.
Ruth named the doll Barbie, after her daughter
Barbara. She also designed the male doll Ken,
which she named after her son.
The Barbie doll is still one of the
bestselling toys in the world.

12. Josephine Cochrane
Josephine Cochrane was born 8th March 1839 in Ohio and died 3rd August
1913, aged 74. Cochrane was the inventor of the first commercially successful
automatic dishwasher. She worked together with mechanic George Butters.
Other attempts had been made to produce a commercial dishwasher but
these had been less successful. Joel Houghton design a hand-cranked
dishwasher and L.A. Alexander designed a gear mechanism that allowed
the user to manually spin the dishes through the water but neither of
these devices were effective.
Cochrane first measured the dishes and built wire compartments
for the crockery. She then added a motor that turned a wheel
inside the dishwasher automatically as hot water squirted up
from the bottom. Cochrane’s design was the first to use water
pressure rather than scrubbers to clean the dishes.
In 1893, restaurants and hotels began putting orders in for
the new automatic dishwasher.
It wasn’t until the 1950s that dishwashers became a
common household utility.

13. Mary Anderson
Mary Anderson invented windscreen wipers.
On a rainy journey to New York, she noticed other drivers having to
open their windows and look out in order to see where they were
going.
She invented a swinging arm with a rubber blade that could be
operated by the driver from inside the vehicle to solve the problem.

14. Jan Ernst Matzeliger
Jan Ernst Matzeliger was born 15th September 1852 in Suriname
(known at the time as Dutch Guiana) and died 24th August 1889.
In 1877, Matzeliger worked as an apprentice in a shoe factory,
crafting shoes almost entirely by hand. This involved making
moulds of customers’ feet, called ‘lasts’ from wood or stone.
Shoes could then be sized and shaped according to the last.
This needed to be done by shaping and attaching the body of
the shoe to the sole by hand, using craftspeople known as
‘hand lasters’. It was considered to be the most difficult
stage of the process.
Matzeliger developed an automatic method for lasting
shoes, named the ‘lasting machine’. This machine
was able to produce up to 700 pairs of shoes a day,
more than 10 times the amount typically
produced by hand.

15. Garrett Morgan
Garrett Morgan was an American inventor,
businessman and community leader.
Morgan invented a number of inventions,
including a protective smoke safety hood
for firefighters to protect them while
dealing with fires and a hair straightening
product.
Most famously, Morgan patented a design
for traffic signals to have a third ‘warning’
signal in 1922 after witnessing a serious
accident at a junction between an
automobile and a horse carriage.

16. Steve Jobs
Steve Jobs designed the iPod in
2001 to satisfy the demand for
music on the move. It was very
popular because it was small
and stylish.
From this, Jobs launched iTunes so
that customers could download
music on to their iPod.
Jobs went on to design the iPhone,
iPad and many other products for
the company Apple, before he died
at the age of 56.

17. George Washington Carver
George Washington Carver was an American
agricultural scientist and inventor.
Carver worked in Alabama, USA to help
farmers grow better quality crops and
improve the soil’s quality so it can be used
again for growing other crops.
Carver also went on to find alternative uses
for peanuts and soya beans, which were
grown in large quantities in the south of the
USA, such as making products like milk, flour,
ink, plastics and soap.

18. Alice H. Parker
Alice H. Parker was born in 1895 in New Jersey and died 1920
(exact dates unknown).
Parker is known for her design of central heating using natural
gas.
Parker’s heating system invention allowed cool air to be drawn
into the system which was then heated through a
heat exchanger, producing warm air that was
put out into the room. Each radiator could have
an independent controlled unit to control the
temperature in each room.
Central heating had been around before Parker
was born but her design was the first to use
natural gas as fuel instead of coal or wood.
