I think Theobald Boehm did but im not 100% sure
No he didn't make the first flute. The flute has a big history behind it. So the last recorded was Theobald Boehm. He made the modern flute in 1832. He made the modern flute we use today.
Theobald Boehm was a Bavarian inventor and musician who perfected the modern flute and improved its fingering system.
A flute fingering chart will give the fingerings (a comprehensive one will also give alternatives) for the flute.

The fingering is: Thumb on hole at the back, and 3rd finger on 2nd hole.
The website linked below has fingering charts and basic instructions for quena, transverse quena, and other similar instruments.
Using a high flat fingering on the flute can make it easier to play certain notes with better intonation and tone quality. It can also help in achieving smoother and more accurate transitions between notes.
Good upper posture for holding the flute, lots of air for playing, ability to manipulate embouchure, and resilience.
