The son and grandson of merchants, Wyld was brought up to regard the career of artist as not suitable for a gentleman.
He posted as a Secretary to the British Consul in Calais, where he met Bonington's teacher Francia.
After a spell in the family wine business, he accompanied a diplomatic mission to Algeria, where he continued his passion for sketching,
Returning to Paris, with many good contacts in art and society, he finally devoted himself to his artistic carreer, exhibiting in the Salon from 1833.
Fifty Algerian sketches were published as lithographs un 1835.
Wyld showed occasionally in London, and gained royal favour, with invitations to Balmoral, but was persuaded in 1855 to exhibit in the Exposition Universelle with the French.
