One of the most famous American poets in the 1940s and 1950s was born in a German immigrant family in Michigan. He studied at the University of Michigan and Harvard University. Rotteck loved nature since he was a child. He built a greenhouse in Michigan, specializing in planting all kinds of plants and flowers, and regarded the greenhouse as "the symbol, birthplace and paradise of all life phenomena". Animals and plants became the main objects of his poetry description. Rotteck wrote many beautiful poems in his life, including Open House (194 1), The Lost Son (1948) and Praise to the End! (195 1), Awakening (1953), Wei Feng (1958), Lamb said, I'm here! (196 1), distant land (1964), etc. , but also about the poet and his writing skills (1965) and diary "burning grass". In 1950s, Rotteck won Pulitzer Prize, National Book Award and Berlin Root Award successively. His works mainly reflect life through the ups and downs of plants, some of which are mysterious and dreamy, reflecting the poet's keen observation of things. Rotleck's poems not only have Eliot's rigorous skills, but also have a relaxed rhythm, a strong personality and a combination of traditional skills. Rotteck taught in universities all his life, which had a great influence on students. Later, many of his students became accomplished poets.
