Du Shi (Chinese: 杜詩; pinyin: Dù Shī; Wade–Giles: Tu Shih, d. 38) was a Chinese hydrologist, inventor, mechanical engineer, metallurgist, and politician of the Eastern Han Dynasty. Du Shi is credited with being the first to apply hydraulic power (i.e. a waterwheel) to operate bellows (air-blowing device) in metallurgy. His invention was used to operate piston-bellows of the blast furnace and then cupola furnace in order to forge cast iron, which had been known in China since the 6th century BC. He worked as a censorial officer and administrator of several places during the reign of Emperor Guangwu of Han. He also led a brief military campaign in which he eliminated a small bandit army under Yang Yi (d. 26).

(en) Du Shi (Hanzi: 杜詩; Pinyin: Dù Shī; Wade–Giles: Tu Shih, w. 38) adalah seorang insinyur, metalirgis, dan politikus Tiongkok pada zaman dinasti Han Timur. Du Shi dikenal karena menjadi orang pertama yang menerapkan kekuatan hidrolik (seperti roda air) untuk mengoperasikan ubub (alat penghembus udara) dalam metalurgi. (in) Du Shi, en chinois traditionnel : 杜詩 ; pinyin : Dù Shī ; Wade : Tu Shih, (date de naissance inconnue - 38) était un préfet chinois de Nanyang en l'an 31 ainsi qu'un ingénieur en hydraulique du temps des Han orientaux. On attribue à Du Shi la première contribution de l'énergie hydraulique à la métallurgie, par l'utilisation d'une roue à aubes pour actionner les soufflets d'un four. Son invention fut utilisée sur les soufflets à piston des hauts fourneaux et des cubilots, ce qui permit l'obtention de fonte en fusion. (fr) 杜詩（前1世纪？－38年），字君公，河內郡汲縣人，東漢官員及發明家，他與東漢蔡倫、張衡、北宋畢昇被譽為中國古代四大發明家。杜詩年輕時有才能，在那里任官為功曹，以公平著稱。更始政權時，被征辟為大司馬府官員。建武元年（25年），一年內三次升遷至侍御史。當時將軍放縱士兵橫行，驚擾百姓。杜詩勸諭蕭廣，蕭廣不知收斂，於是擊殺蕭廣，回京後奏報光武帝。光武帝派他巡視河東，去招降和誅殺反叛的賊人楊異等。杜詩到達大陽，聽說賊人企圖北渡，于是与長史迅速焚毀船只，調集部署郡中士兵，派騎兵突襲賊兵，殺死楊异等人，賊兵因此被消滅。拜授為成皋縣令，任官三年，政績優異。又遷升至沛郡都尉，再轉任汝南都尉。所到之處，皆有政績。建武七年（31年），升任南陽郡太守。他生活節儉，施政清正平和，以誅除強暴建立威信，擅長計划謀略，節省和愛惜民役。又設計制作水排（水力鼓風機），以水力傳動機械，使皮製的鼓風囊連續開合，將空氣送入冶鐵爐，鑄造農具，用力少而見效多，便利百姓。此外，還修建池塘，開墾土地，使郡中百姓生活豐足。當時人們把他比作召信臣，所以南陽人贊頌他：“先有召父，后有杜母。”杜詩自認沒甚功勞，不應長期任大郡肥缺，請求他遷以讓職位給功臣，於是上疏請辭。光武帝愛其人才，不讓他請辭。 (zh)
