1889 年，李四光出生于湖北黄冈。1904 年，他赴日本学习造船；1913 年，赴英国伯明翰大学学习采矿学，一年后改学地质学。1923 年，李四光提出蜓科古生物鉴定方法，并鉴定大量化石标本，写成了他的第一部科学巨著——《中国北部之蜓科》，成为享誉世界的古生物地质学家。

In 1889, Li Siguang was born in Huanggang, Hubei Province. In 1904, he went to Japan to study shipbuilding. In 1913, he went to the University of Birmingham in England to study mining and one year later switched to geology. In 1923, he proposed the method of identifying the family Petaluridae and identifying a large number of fossils specimens, which contributed to his first scientific masterpiece Petaluridae of Northern China, making him a world-famous paleontological geologist.

20 世纪 20 年代至 40 年代，李四光创立地质力学，将其引入地壳构造和地壳运动规律的研究中，开辟了一条解决地壳构造和地壳运动问题研究的新途径。1948 年，李四光代表中国地质学会到伦敦参加第十八届国际地质大会，他是其中唯一的亚洲人，这说明当时中国的地质科学已经在世界地质科学领域占有了一席之地。从 1953 年到 1959年，在李四光的地质理论指导下，经过六年艰苦卓绝的勘探工作，我国终于在松辽平原上钻探出了一口工业油井。随后不久，勘探队又先后发现了大庆、胜利等油田，一举摘掉了“中国贫油”的帽子。

From the 1920s to 1940s, Li Siguang fathered the theory of geomechanics and introduced it for study of the laws of crustal structure and movement, opening up a new way to solve problems related to crustal structure and movement. In 1948, Li Siguang was a representative of the Geological Society of China to attend the 18th International Geological Congress in London. He was the only Asian participant, which indicated that Chinese geological science had already gained recognition in the field of global geological science at that time. From 1953 to 1959, under the guidance of Li Siguang’s geological theory, after six years of arduous exploration work, China finally drilled an industrial oil well in Songliao Plain. In the following short time, the exploration team discovered Daqing, Shengli and other oil fields one after another, and shed the label of “China’s poor in oil resources” for many years.

1920 年起，李四光长期担任北京大学地质系教授、系主任，为发展中国地质事业、提高中国地质科学水平输送了大批优秀的地质工作者。1928 年，他参与筹建武汉大学。1952 年起，他亲自主持了北京地质学院［现为中国地质大学（北京）］和东北地质学院（现为吉林大学地球科学学院）的建院工作。在他的关怀下，又扩大建立了成都地质勘探学院（现为成都理工大学）以及许多中等地质技术学校，为我国开展地质勘探、地质科研培养了大量的各类技术骨干。

From 1920, Li Siguang served as a professor and department head in the Department of Geology at Peking University for a long time. He contributed greatly to China’s geological prospects and the improvement of its scientific level by producing a large number of excellent geological workers. In addition, in 1928, he participated in the establishment of Wuhan University. From 1952, he personally presided over the establishment of Beijing Institute of Geology (now China University of Geosciences) and Northeast Institute of Geology (now College of Earth Sciences, Jilin University). With his care, Chengdu Institute of Geology (now Chengdu University of Technology) and many secondary technical schools of geology were expanded and established, and a large number of technical backbones were trained for geological exploration and scientific research.

李四光在音乐上也很有造诣，不仅小提琴拉得出神入化，1920年，他在巴黎创作的小提琴曲《行路难》还是中国人创作的第一首小提琴曲。

Li Siguang was also very accomplished in music. He not only played the violin superbly, but also his violin piece Hard Is the Way of the World created in Paris in 1920 was the first one by a Chinese.

1988 年，《中国现代科学家》纪念邮票发行，李四光入选第一组第一位人物。2009 年 9 月，李四光被评为“100 位新中国成立以来感动中国人物”，同年 10 月 , 经国际天文学联合会小行星命名委员会批准 , 中国科学院国家天文台将编号 137039 的小行星永久命名为“李四光星”，向世界昭示中国地质工作者对地球科学发展和进步的贡献。

In 1988, a series of commemorative stamps of “Modern Chinese Scientists” were issued, and Li Siguang was selected as the first person in the first group. In September 2009, Li Siguang was honored as one of “100 People Who Touch China Since the Founding of New China”; in October, the National Astronomical Observatory of Chinese Academy of Sciences permanently named the asteroid No.137039 “Li Siguang Star”, showing the world the contribution of the Chinese geologist to the development and progress of earth sciences.

李四光的一生，一直在为国争光而疾走，为国争气而拼搏，为实现救国强国梦而奋斗，他是名副其实的地质之光。

Throughout his life, Li Siguang had been dedicated to bringing glory to the country and striving to fulfill the dream of saving and strengthening the nation. He is truly a star in geology.
