The artist who traveled to the Louvre in hopes of painting one gallery containing several masterpieces, only to find the gallery filled with contemporary works was Samuel E.B. Morse. <span>After having established his reputation as a portrait painter, in his middle age Morse contributed to the </span>invention<span> of a single-wire </span>telegraph<span> system based on European telegraphs. He was a co-developer of the </span>Morse code<span>, and helped to develop the commercial use of telegraphy.</span> I hope that this is the answer that you were looking for and it has helped you.
I believe the correct answer is C. Copley.
Portrait d'apparat— a Rococo technique of portraying the
subject with objects associated with him in his daily life—was used by American
painter John Singleton Copley, whose portraits and historical subjects are generally
acclaimed as the finest artist of colonial America. The use of Portrait d’apparat
gave his works liveliness and acuity which was not usually associated with
XVIII century American painting.
