He moved to Bent & Parker, a maker of army supplies and whistles in Birmingham. In 1870, aged 22, he started his own business with younger brother James. In 1883 Hudson began tinkering in his toolshed to make gadgets to sell, including whistles. After observing local police struggling to communicate with rattles, he realised that his whistle could be used as a tool. As the story goes, Hudson, a violin player, accidentally dropped his violin and it shattered on the floor. Observing how the discordant sound of the  breaking strings travelled, Hudson had the idea to put a pea in the whistle. This gave it an ear splitting rattle that could grab attention even a mile away. After a demonstration at Scotland Yard, Hudson had his first sale. This 1884 contract with the police gradually made Hudson the largest whistle manufacturer for British Empire police forces, military, sports, railways and many others. By the 1890s, Hudson faced the rise of many competitor makers and companies.

Starting 1909  at a new facility in northern Birmingham at 244 Barr St., Hudson expanded to more markets in Europe and overseas, with an office in Paris, a large 1910 French catalogue, and new connections with United States sporting goods companies and distributors. Hudson was left with just one British competitor, A De Courcy & Co, from 1909 to 1927. In 1912, the company made whistles that were used by the crew on board the RMS "Titanic".

This was the end of the golden age of whistle making. 1930–2000. At the beginning of this period the company faced competition from whistles made of tin, plastic and cast base metal materials made in Germany, Japan, USA and other countries. On 26 October 1940, the factory received a direct hit from a German air raid. No one was injured, but the factory suffered major damage. Air Raid Precautions whistles were  made during the next few years and dated whistles for army, navy and Royal Air Force equipment and for Civil Defence. In 1949 the firm was re-constituted as J. Hudson & Co. (Whistles) Ltd. Leon C. Hudson became its first managing director. The 1950s and 60s marked growing demand for Hudson sports whistles, Olympics and other sport events on five continents.

Topman became an assistant general manager, and about 40 years later his son, Simon Topman, became the owner and the managing director of the company, starting the fourth period of company developments.
