John Mawe

[2] Brown & Mawe was the name of the retail business near Covent Garden in 1797 which sold objects created from Derbyshire marble at the factory in Derby.

[4] In 1800 he owned the Royal Museums spar shop in Matlock Bath which, through his agent, he was to enter into dispute with Thomas Pearson concerning surrounding mines.

[5] In August 1804 he started on a "voyage of commercial experiment" to Rio de la Plata funded by Portugal's Prince Regent.

He accompanied the expedition under John Whitelocke to Buenos Aires, and on his return to Montevideo purchased a schooner and sailed to Brazil, putting in at various ports on the way, including the island of Santa Catarina.

He was well received in Brazil by the prince regent, who gave him permission to visit the diamond mines of Minas Gerais and other parts of the interior during 1809–10, and also granted him access to the government archives.

[7] Mawe's principal work was the account of his South American voyage, Travels in the Interior of Brazil, London, 1812;[8] Philadelphia, 1816; 2nd edition, 1823.

He appears also to have issued at some time Directions to Captains of Ships, Officers, and Travellers; particularly to those engaged in the South Sea Fishery (for collecting shells).
