Explanation

Lazlo Biro invented the ballpoint pen in the 1930s. His design used a tiny ball that rotated to pick up ink and deposit it on paper, solving the problem of ink flow that earlier pens had. Oscar, Wilson, and Waterman were associated with other inventions or pen improvements but not the ballpoint mechanism.
