Did Garrett have problems inventing the gas mask?

Garrett Morgan faced several challenges while inventing the gas mask, primarily due to limited resources and the need for effective design. His initial prototype required significant experimentation to ensure it provided adequate protection against toxic fumes. Additionally, gaining recognition and support for his invention was difficult, as many were skeptical about its effectiveness at the time. Despite these obstacles, Morgan's perseverance led to the successful creation of a gas mask that would later be used in various emergency situations.
