Henry Joseph Round was a great man.

His 85-year life was packed with achievement and adventure, crammed full of invention and creation.

Described in one publication as having 'shaped the course of British history' and another as being the 'father of British broadcasting', he was awarded the Military Cross in the First World War and the coveted Armstrong gold medal from the Radio Club of America in 1952.

His determination to progress the world of electronics and radio further and further into the unknown was relentless and astonishing, resulting in the registering of 117 patents during his career.

He has been described as the 'unrecognised' pioneer and, while it is true he didn't receive any civil honour like a knighthood or make front page headlines with celebrity status, he was recognised as a genius within the electronics field and, if you dig deep enough, one can find plenty about him on the invention that would have excited him beyond belief - the internet, the world wide web.

Whether working in London or Chelmsford as Guglielmo Marconi's personal assistant and chief engineer; constructing radio stations in the upper reaches of the Amazon river; working with the Americans in New York or earning a secret name - Captain X - among the shadows of British Intelligence, Henry Round was constantly pushing boundaries in the world of radio and broadcasting.

Even with this insatiable desire to invent, he was a caring and generous family man, devoted to his seven children and numerous grandchildren.

Before returning to look at his professional life, it is important to note that the balance he achieved between work and family meant he was very much loved as father and grandfather.

As far as his work is concerned, his family are immensely proud of this brilliant man - a pride that constantly rises as more is discovered about his life.

To fully understand the work of Henry Round requires a deep dive into a world of thermionic valves, triodes, oxide coated filaments, anodes, wireless telephony, amplitude control modulation systems, receivers, transmitters, magneto-strictive devices, nickel transducers, oscilloscopes and a host of other devices and processes in a lexicon unintelligible to most people.

Maybe his own understanding about how complex was this work is demonstrated in a quote from Round's acceptance speech when receiving the Armstrong Medal. Talking technically about valves, he made the aside: "or what my wife calls them, bottles.'

Talking, or reading, technology - Round's natural language - is best followed in more academic documents than this one but there are key episodes in his professional life that must be highlighted.

In between the wars he was prolific in his work, focussing much of his time on valve and microphone development.

Between 1921 - 31 he was chief of Marconi Research and was involved in the famous wireless broadcast of singer Dame Nellie Melba in 1920 and, in 1924, his Marconi-Sykes magneto phone (microphone) facilitated the first outside broadcast of a songbird, a nightingale singing as cellist Beatrice Harrison played nearby.

He developed valve after valve; he directed the installation of wireless transmitters; he produced a gramophone recording system and designed a large audience public address system which was used to relay King George V's speech at the Wembley Exhibitions and he registered patents on synchronising sound with pictures on cinema films.

And so, he continued his work as a persistent inventor and creator.
