鄧達智於加拿大完成經濟學士課程後，往英國攻讀時裝設計，畢業後於歐洲任時裝設計師。1985 年回港成立自己的設計公司，推出首個個人系列─針織為主的女裝。除系列設計外，鄧亦為多間機構設計形象及制服，如香港國際機場、港龍航空公司、中國銀行及將於 2007 年年底為地鐵及九廣鐵路公司合併的所有員工設計制服。曾獲得海內外多個獎項，包括 2005 年獲香港傳藝中心頒發「十大傑出設計師大獎」、2006 「大中華傑出設計大獎」。其設計為澳洲動力博物館、英國維多利亞和艾伯特博物館以及香港文化博物館收藏。

鄧氏早期醉心地中海沿岸民族服裝及風景，引為靈感泉源；隨後，以中國及亞洲民族衣著特色為設計依歸。近年，他的設計源自香港本土歷史及街頭文化。作品中如199 7年的「九龍皇帝」及 2007 年的「九龍皇帝十年回顧」等，皆教人印象深刻。

William Tang obtained his bachelor’s degree in economics in Canada, then went to U.K. to study fashion design. He joined the fashion industry in Europe after graduation and returned to Hong Kong to start his own design house in 1985. His debut collection was primarily ladies knitwear. Apart from working on his own label, Tang also designed corporate image and uniforms for many organizations, including Hong Kong International Airport, Dragonair and Bank of China, and the new MTR uniform there would change by the end of 007. After series of awards received from HK, China and oversea, in 2005. Tang was awarded ‘Ten Outstanding Designers Award’ by Hong Kong Communication Art and Design Centre and also “Outstanding Greater China Design Awards” in 006 . His works are among the collections of Powerhouse Museum of Australia, Victoria and Albert Museum of U.K. and Hong Kong Heritage Museum.

In the early years, Tang often sought inspiration from ethnic costumes and sceneries of the Mediterranean coasts; later, designed featured ethnic characters of China and Asia. In recent years, his works reflect local heritage and street culture of Hong Kong. Works like ‘The King of Kowloon’ in 1997 and ‘King of Kowloon Revised’ in 2007 have made great impacts.
