Like Abramson, Engstrom was a pioneer, but more specifically, he was one of the Microsoft engineers who, along with colleagues Alex St. John and Craig Eisler, made Windows gaming viable and even developed the DirectX API. That has since seen several evolutions, the latest iteration of it being the DirectX 12 (DX12) Ultimate.

From there, several of you know what happened next; with DirectX, the API effectively made gaming on Microsoft’s Windows OS the preferred choice for PC Gaming and even laid the foundation for what would later be Microsoft’s Xbox consoles. (Source: Engadget, WSJ // Image: WSJ)
