EDWARD DAVY

Name: Edward Davy                                                                         
Born: 16 june 1806                                                                       
Died: 26 January 1885                                                                     
                                                                                         
Edward Davy (June 16, 1806 - January 26, 1885), was an English physician,                 
scientist and inventor, chemist and promoter of the telegraph, was born on               
16 June 1806 at Ottery St Mary, Devon, the eldest son of Thomas Davy, a surgeon,         
and his wife, Elizabeth Boutflower. He was educated at the Revd Richard                   
Houlditch's school at Ottery St Mary and at the school of his maternal uncle in           
Tower Street, London. ... His interests lay in the general sciences,                     
particularly chemistry and electricity, and a catalogue of instruments, appended         
to his Experimental Guide to Chemistry, published in 1836, includes several               
devices invented by him in the list of goods and instruments for sale. In 1836           
he patented Davy's diamond cement, an adhesive for mending china and glass, from         
which he gained a small annual income until he sold the rights to the process."           
                                                                                         
Also in 1836, Davy published Outline of a New Plan of Telegraphic                         
Communication, and in 1837 he carried out telegraphic experiments in Regent's             
Park. ... He demonstrated a working model of his telegraph that year and a               
needle telegraph in the Exeter Hall in central London for several months in 1838.         
He applied for a patent for his telegraph, which was granted on 4 July 1838               
after the solicitor-general asked Michael Faraday's advice as to whether it               
constituted a different mechanism from that of (Sir William Fothergill) Cooke             
and (Sir Charles) Wheatstone, patented on 12 June 1837. Davy managed to interest         
two railway companies, the Birmingham Railway and the Southhampton Railway, in           
his telegraph, but left England for Australia before developing a practical               
system for completing negotiations, which he left in the hands of his father and         
a friend, Thomas Watson, a London dentist. Eventually his patent was bought by           
the Electric Telegraph Company in 1847 for 600. Although his telegraph was               
never developed, Davy was important for popularizing to the general public the           
concept of telegraphy, and was the first to develop a relay system ."                     
                                                                                         
But Davy was clearly the originating inventor of the Telegraph despite his               
several difficulties with pursuit of his projects to their final "approvable"             
conclusions; and not Morse, who wasn't even originally granted a patent for his           
version until 1840 ? conveniently, one year after Davy had abandoned his                 
pursuits entirely in this area.                                                           
                                                                                         
It clearly states that Morse's first patent of 1840 was annulled ("for which             
letters-patent were granted on the 20th June, 1840, which letters-patent were             
surrendered and rescinded on the 15th day of January, 1846, which last letters-patent     
are hereby cancelled on account of a defective specification"), but re-granted           
in 1849; and the "evidence" that was presented at the trial, actually accepted           
the "fact" that Morse had these ideas in his "mind" as early as 1832 (and of             
course, two years after "the researches of Professor Joseph Henry on the electro-magnet, 
in 1830,").
