We review the stories of two great 20th century inventors. Guglielmo Marconi (1874 - 1937) was an Italian radio pioneer. Edwin Land (1909 - 1991) was the American chemist who invented the Polaroid Camera.

William Shakespeare (1564 - 1616) is considered the greatest playwright of all time; Jonathan Swift (1667 - 1745), the greatest satirist. What can we mere mortals learn from these literary giants? You might be surprised.

The stories of two very different inventors. One was forced to innovate and the other stumbled on a great idea by chance. Daniel

Peter invented milk chocolate and Percy Spencer created the microwave oven.

The stories of two contrasting inventors and innovators who made contributions to the allied efforts in World War II.  Both featured in films.  Hedy Lamar (1914 - 2000) was an Austrian actress and Hollywood star who was called the most beautiful woman in the world.  She invented a radio technique still used today in wifi and bluetooth technologies.  Barnes Wallis (1887 - 1979) invented the bouncing bomb used by the RAF in the dam busters raid of 1943 which breached the Mohne and Eder dams in Germany.  He was played by Michael Redgrave in the 1955 film, the Dam Busters.

What ideas and inspiration can we glean from two English entrepreneurs and innovators?  Sir Charles Dunstone (born 1964) is the founder and former chariman of Carphone Warehouse, at one time the world's largest mobile phone retailer. Rob Law (born 1982) is the inventor of the Trunki, a ride-on suitcase for children which was savaged on Dragon's Den.

Paul Sloane relates the stories of two influential innnovators who each took an idea from one field and applied it with great effect in another.  Clarence Birdseye (1886 - 1956) was an American scientist who created the frozen food industry.  Jorge Odon (born 1952) is an Argentinain car mechanic who invented a device which can help save the lives of mothers and babies.

We consider the lives and achievements of two great inventors, who had contrasting experiences of fame and fortune. Thomas Edison (1847 - 1931) was probably the greatest inventor of all time.  Trevor Baylis (1937 - 2018) was the British inventor of the clockwork radio. 

Let's celebrate the achievements of two outstanding Scottish innovators.  Both were called Allexander and both had a tremendous impact on our lives. Alexander Graham Bell was the inventor of the telephone. Sir Alexander Fleming was the doctor who discovered penicillin.

We gain insights and inspiration from three great American movie makers and innovators.  Walt Disney (1901 - 1966) creator of ground-breaking cartoon films and founder of Disneyland.  The comedian, actor, writer and director, Woody Allen (born 1935).  And Steven Spielberg (born 1946), the most commercially successful film director of modern times. 

Let's go way back in history and consider the achievements of two geniuses of ancient Greece.  Pythagoras (570 - 495 BC) was a mathematician and philosopher.  Archimedes (287 - 212 BC) was a mathematician, engineer and inventor.  They laid the foundations of our understanding of mathematics and their theorems are taught in schools to this day.
