UK Firsts Research

All well and good looking at lots of lovely stamp design but what I really need is some decent content for my series of stamps, so I decided to do some initial research into scientific discoveries, inventions and medical breakthroughs:

There are some interesting ones but what I am finding is that there is a distinct disparity between the firsts. 

Some of my favourites form the above notes are:

Inventions:

Cats Eyes - Percy Shaw

Corkscrews - H.S. Heeley

Television - John Logie Baird

Light Bulbs - Humprey Davey

Wind Up Radio - Trevor Bayliss

The Mini (Car) - British Motor Corporation

Adjustable Spanner - Edwin Beard Budding (brilliant name!) 

Medical:

Penicillin - Alexander Fleming

Periodic Table - John Newlands (Mendelev later improved on Newlands original)

Colour Blind Diagnosis - John Dalton

Scientific:

Theory of Evolution - Charles Dawin

Diagnostic Ultrasound - J. W. Wild

Splitting the Atom - Ernest Walton and John Cockroft 

Misc.:

Crossword Puzzles - Arthur Wynne

Marshall Amplifiers (first to use large high-gain valves = loud) - Jim Marshall

More digging to be done to break down into distinct series', but plenty to work with for now (in between the pesky dissertation!)
