Who invented the two-cycle gasoline engine?

The two-cycle gasoline engine was developed in the late 19th century, with significant contributions from various inventors. While it is difficult to attribute its invention to a single individual, German engineer Nicolaus Otto is often credited with early advancements in engine design that paved the way for the two-stroke engine. Another key figure is the American inventor George Brayton, who patented a two-cycle engine design in the 1870s. However, the concept evolved through multiple innovations and refinements over time.
