William A. Arnold discovered many phenomena in photosynthesis. In 1932, together with Robert Emerson, he provided the first experimental data that led to the concept of a large antenna and a few reaction centers (photosynthetic unit); in 1935, he obtained the minimum quantum requirement of 8-10 for the evolution of one O2 molecule; in 1951, together with Bernard L. Strehler, he discovered delayed fluorescence (also known as delayed light emission) in photosynthetic systems; and in 1956, together with Helen Sherwood, he discovered thermoluminescence in plants. He is also known for providing a solid-state picture of photosynthesis. Much has been written about him and his research, including many articles in a special issue of Photosynthesis Research (Govindjee et al. (eds.) 1996); and a biography of Arnold, by Govindjee and Srivastava (William Archibald Arnold (1904-2001), 2014), in the Biographical Memoirs of the US National Academy of Sciences, (Washington, DC). Our article here offers a glimpse into the everyday life, through stories and photographs, of this remarkable scientist.
威廉·A·阿诺德发现了光合作用中的许多现象。1932年，他与罗伯特·爱默生一起提供了首个实验数据，促成了大天线和少数反应中心（光合单位）概念的提出；1935年，他得出产生一个氧分子的最小量子需求为8至10；1951年，他与伯纳德·L·斯特勒一起发现了光合系统中的延迟荧光（也称为延迟光发射）；1956年，他与海伦·舍伍德一起发现了植物中的热致发光。他还因提供光合作用的固态图景而闻名。关于他及其研究已有诸多著述，包括《光合作用研究》特刊中的许多文章（戈文德吉等人（编），1996年）；以及戈文德吉和什里瓦斯塔瓦所著的阿诺德传记《威廉·阿奇博尔德·阿诺德（1904 - 2001）》（2014年），载于美国国家科学院《传记回忆录》（华盛顿特区）。我们这里的文章通过故事和照片，让大家得以一瞥这位杰出科学家的日常生活。
