The answer
Johann Jakob Griesbach. In 1776 he published the three Gospels in parallel columns and called the book a "Synopsis," the word scholars still use for such tables. Set in columns, a story like the healing of the paralyzed man can be read across all three at once (Mark 2:1-12; Matthew 9:1-8; Luke 5:17-26).
Why it’s interesting
In 1789 Griesbach went further and proposed an order of writing: Matthew first, then Luke, then Mark. On his view Mark is mostly a digest of the places where Matthew and Luke agree.
