Final answer:
The institution to which Louis Armstrong was sent for rehabilitation after firing a gun during a New Year's Day celebration in 1913 was named the New Orleans Colored Waifs' Home for Boys. When recalling this period of his life later on, Armstrong referred to it as the "orphanage."
Explanation:
Louis Armstrong was sent to the New Orleans Colored Waifs' Home for Boys, an institution aimed at caring for neglected or abandoned children. This was a pivotal moment in Armstrong's life as it introduced him to music, particularly the cornet, laying the foundation for his legendary career in jazz. His stay at the institution exposed him to formal music education and provided a safe haven that steered him away from a troubled path.
Referring to the institution as an "orphanage" in later years highlights Armstrong's emotional connection to the place and the impact it had on shaping his identity and career. Despite the challenges he faced early in life, his time at the Colored Waifs' Home became a transformative period, setting the stage for his remarkable journey as a musician.
The significance of this institution in Armstrong's life goes beyond mere rehabilitation; it served as a catalyst for his passion for music and laid the groundwork for his future success. His experiences there not only shaped his musical talents but also instilled in him a sense of discipline and dedication that defined his illustrious career.
