Compare this with wireless charging

Good story. Compared with wireless charging, which is very short range (in spite of Nikola Tesla's multiple experiments attempting otherwise), RF comms provided a service that no wired telegraphy could.

I'll grant the lack of a physical connector, which can be delicate, would be an advantage of wireless charging. But as much as the amount of wasted energy by all those wired chargers left plugged in today is being hyped, imagine how much more energy these wireless charges will waste.

It is a cool story. I love reading about history. I asked the author Keith where he got this idea of writing about Marconi.

He wrote back to me:

A few years ago at NI Week one of the presenters told the Dr Crippen story. It fascinated the audience. I meant to write about it then but just got busy and forgot but always remembered the story. 

Finally I had time and started researching it last week. Turns out there have been a few movies and documentaries about the Dr Crippen story and a book, Thunderstruck, written a few years ago. I read the book, and other articles and websites, and it occurred to me to check to see if it was same radio on Titanic. It was, so I tied it all together.

The book "Thunderstruck" is definitely recommended reading.  It focuses on the dual stories of the Crippen murder and Marconi's struggle to develop and commercialize his wireless telegraphy system.  While written for a general audience, it will likely be especially appreciated by this site's technical audience.

Interestingly, regarding the murder and subsequent conviction and execution of Hawley Crippen, more recent evidence in the form of DNA analysis has some forensic experts suggesting that Crippen was in fact innocent.

Yes, I read about that too. The "human" remains that were found under Dr. Crippen's cellar floor were not readily identifiable - in fact, they weren't even sure if the remains were human. There were no bones, extremities, or organs. My understanding there was only "skin". 

Dr. Crippen's wife had lost her baby years before while they lived in America and the procedure left a scar on the skin of her tummy. THAT SCAR was the PRIMARY evidence that the prosecution used to support their claim that it was his wife. 

However, the defense argued that a scar can not have hair growing out of it, which it did, but somehow they lost this argument. I'd welcome any doctors comments about scar tissue and hair being able to grow out/thru scar tissue (why? why not?). 

I think the strongest evidence that he did murder her, was the fact that she never showed up later in life. Where'd she go? Dr. Crippen said that she died while in the US and was cremated, but no crematorium ever acknoledged that! He said she was cremated somewhere in California. I'm would expect that experts have searched exhaustively for her death and cremation certificate and never found it.

Apparently when questioned by the police Crippen recanted the story about his wife dying in the U.S. and explained that in fact she had run off with another man, and that he had made up the story to save face.

Great story!  The ease of today's worldwide connectivity is taken for granted by most who use these everyday services, the result of much intensive engineering effort by many.

But I still remember back in the 60's when my ham radio licence finally arrived in the mail, and my first Morse code CQ on 40 meters from my home-brewed transmitter raised a QSO from Michigan.  That was a real thrill, a home-built radio apparatus that could send electromagnetic waves all over the world.

Thanks for the blog. I really enjoyed it. The vast majority of the books that I read are on scientific/engineering history and this was definitely in the same vein. More please!

A rap for G. Marconi

I used AutoRap, by Smule (iphone apps) to make this. Simply read the first paragraph of the article. Software did the rest!

Good marketing tool, and a little humorous to boot.

On my PC the image is cut off and you can hardly see the tower.  If you right click and then click "Open image in new tab" you'll get the full thing.  (this in Chrome - does not work in IE, but if you click reply, you get a bigger version showing the whole tower, then just go back).

After Marconi's theft of information from Tesla,I personally can give hime no credit for anyhthing wireless.His knowledge was built upon a theft of intellecual property from Tesla,and was not discovered until after Tesla's death.Likewise with his wirelss telephony.It is probably another heretofor undiscovered theft from Tesla.Tesla had already invented wireless control of model boats and cars before this,so how far of a stretch is it for wirless telephony? It should have been named Marconi-phoney. IMHO,just another famous thief.

Marconi does deserve some credit for doing something with it, but it does appear that Tesla was the real inventor.    How often has this happened even up to today, the marketing guys get the credit and the $$...

Sorry,I can not even give a tip of the hat to Marconi.He was working with the capital from "his" radio,and Tesla was starving.Bet Marconi never lost a minute's sleep while living high on another man's genius.

Marconi died rich and famous,Telsla died poor and broken.He did not even get the satisfaction of justice in the patent lawsuit.What good is a posthumus award if you have no family to collect?

Marconi vs Tesla

Hi Keith,

  This is Richard (Rick) Lyons, your fellow instructor at Besser Associates.

(I hope all is well with you.)

I've been reading a book about Nikola Tesla.

History books claim that Italian experimenter Guglielmo Marconi invented radio. The fact is, the first person to implement radio transmission and reception was the enigmatic American engineer Nikola Tesla in 1895. In late 1901, with the backing of wealthy benefactors, Marconi became famous for transmitting and receiving Morse code signals across the Atlantic Ocean. What wasn't advertised was the fact that Marconi used Tesla-invented oscillators for that transatlantic demonstration. Battles over patents raged between Tesla and Marconi for decades. With the drop of their gavel in 1943, a few months after Tesla's death, the U.S. Supreme Court upheld patent number 645,576—Tesla's original radio patent. Sadly, historians have ignored that court decision.

Hi Rick,

 

Great hearing from you. And I agree with your and most of the comments posted here about Tesla being robbed. I pointed out in the 1st paragraph that the patents were later awarded to Tesla, (too late and too little - Tesla never married and had no family, very sad really). At the time, Marconi was able to get it his way and was awarded the nobel prize in Physics. From what I read though, Tesla had invented several of the parts, the oscillator, etc., but Marconi put them together with some refinement (although Tesla did this too), but somehow Marconi was able to be more successful at it. From what I've read, it looks like Tesla was an OCD genius with a photographic memory, but struggled with running a business and company. The poor guy was robbed blind by Edison as well.

Kind of like what Steve Jobs did, right (The Blind Hacker Who Inspired Apple). Steve didn't invent the Blue Box :) , but he turned it into a product and then used it to leverage into the creation of Apple. 

 

I guess I'll have to do some stories on Edison and Tesla...foreshadowing.

Just to even the playing field, here is a picture of Tesla's Tower.

His intent was to use the Earth's magnetic filed as a carrier to transmit power wirelessly.

Funny thing after he died, the Government quickly disassembled and destroyed all of the towers.Only one sphere from a tower remains in the Smithsonian.

Reportedly, he suceeded, but since there would be no way to meter the usage,it was defunded.All of his notes were confiscated and classified.

Ther are a few remaining towers in Russia,but photos of them are very rare.

Tesla also thought he had caused an earthquake through stiumlating the earth at its natural frequency.  The man was way too ahead of his time but he had his demons, one of which was his lack of business sense.  He invented so much and yet died broke and alone, truely sad that a man who did so much ended up "looking" like a failure.  Don't forget the AC vs DC fight he had with his employer Edision..  AC transmission of power (as we all know now) was the best way to go and the only way for long distance.  It says alot about Edision's pride that he could not accept being wrong.

Very interesting story. Some are lucky others invest as much but their Titanic misses the berg ;-) ...


BTW: I'm not a native speaker, but at least to me the sentence about the largest loss of life in peace time sounds wrong as unfortunately there have been peacetime maritime disasters with many more victims. If I recall correctly there was an Asian Ferry which killed above 4000 people when sinking totally overloaded. So the statement would have to read ... largest loss of life AT THAT TIME, not "in modern history" (why the limitation to _modern_ history is necessary is another such question) ...

You are correct. Here's link to top 10 catastrophic shipwrecks. You are referring to MV Dona Paz - listed as #1. http://listverse.com/2008/07/26/top-10-catastrophic-shipwrecks/ Although the claim was that over 4,000 ppl were on board, the manifest showed around 1500. But in any case, Titanic is #5. Thanks!

I helped a skorea businesswomen by internet, she had lost her wallet and ID in China,

Her document was picked up by a bus driver, no one know these strange words, I copy her document and sent to a korea buddy of mine on the net, He translated the doc into English and return me and I dispatched it to bus company and find the woman who was very anxious.

She was delight for the lost doc.
