Answer:
Brass matrix
Explanation:
The linotype machine invented by Ottmar Mergenthaler, a German immigrant, later came to be known as an inventor in America. He invented the first mechanical typesetting machine that was able to use type metal to complete lines. This machine needed matrices, which consist of small brass pieces that have edges indented with characters that are grouped into lines to produce text.
