Who adapted McDonald's two arches into the modern golden-arches logo in 1962?

Jim Schindler adapted McDonald's two architectural arches into the modern golden-arches logo in 1962.

The change marked an important shift in McDonald's branding. Earlier arches were associated mainly with individual restaurant buildings, while Schindler's design turned them into a compact graphic symbol that could work on signs, packaging, stationery, and advertising.

The resulting emblem used the arches to create a stylized letter M. Although the symbol developed from Meston's building designs, it was not simply a drawing of one restaurant façade. It was a deliberate corporate identity system for a rapidly expanding chain.

People often confuse the architect of the original arches with the designer of the later logo. Meston created the architectural concept; Schindler is credited with combining the arches into the iconic mark used by McDonald's.
