William Ellsworth "Dummy" Hoy was a professional baseball player who made significant contributions to the sport during his career. Born on May 23, 1862, in Houcktown, Ohio, Hoy was deaf from a young age, which led to his nickname "Dummy," a common moniker at the time for individuals who were deaf. Despite the challenges posed by his deafness, Hoy became one of the most accomplished and respected players of his era.

Hoy began his professional baseball career in 1886 with the Oshkosh club of the Northwestern League. His major league debut came two years later in 1888 with the Washington Nationals of the National League. Over the course of his career, Hoy played for several teams, including the Buffalo Bisons, St. Louis Browns, Chicago White Sox, and Cincinnati Reds, among others. He was primarily an outfielder, known for his speed, defensive skills, and strong throwing arm.

One of Hoy's most notable contributions to baseball was his role in the development of hand signals for safe and out calls. While it is not definitively documented that Hoy was the sole reason for the adoption of these signals, it is widely acknowledged that his presence in the game and the communication challenges he faced as a deaf player influenced the use of hand signals by umpires, making the game more accessible for deaf players and fans alike.

Throughout his career, Hoy compiled impressive statistics. He accumulated over 2,000 hits, scored over 1,400 runs, and stole over 600 bases. His batting average was .287 over his career. Hoy was also known for his discipline at the plate, drawing a significant number of walks, which contributed to his high on-base percentage. His prowess on the basepaths was notable; he led the league in stolen bases three times during his career.

Hoy's defensive skills were equally remarkable. He was known for his ability to cover a lot of ground in the outfield and for his accurate and strong throwing arm. These attributes helped him to record a significant number of outfield assists, further establishing his reputation as a top-tier defensive player.

After retiring from playing, Hoy continued to be involved in baseball and worked to promote the sport among the deaf community. His legacy in the game is remembered for breaking down barriers for deaf athletes and contributing to the evolution of baseball through the adoption of hand signals.

Despite his achievements and contributions to the sport, Hoy has not been inducted into the National Baseball Hall of Fame, a point of contention and ongoing discussion among baseball historians and fans. William "Dummy" Hoy passed away on December 15, 1961, but his impact on the game of baseball remains significant, both as a pioneering athlete who overcame challenges to excel at the highest level and as a catalyst for change in how the game is communicated and played.
