Percy Edwin Ludgate (1883–1922) is notable as the second person to publish a design for an Analytical Machine, the first after Babbage's “Analytical Engine.” We outline the initial results of the first new investigation into the work and life of Percy Ludgate since Randell's papers of nearly 50 years ago and nearly 100 years after Ludgate's death. First, we examine the principles of his machine and how it was constructed and worked. Second, we outline his life. We present a range of new material, including two significant discoveries, one concerning Ludgate's machine and the other his family.

珀西·埃德温·卢德盖特（Percy Edwin Ludgate，1883-1922年）是第二位发布分析机设计的人，这是巴贝奇（Babbage）的“分析引擎”之后的第一位。我们概述了自Randell在近50年前和Ludgate死后将近100年的论文以来，第一次对Percy Ludgate的工作和生活进行的新调查的初步结果。首先，我们检查他的机器的原理以及它的构造和工作方式。其次，我们概述了他的生活。我们介绍了一系列新材料，其中包括两项重要发现，一项涉及Ludgate的机器，另一项涉及他的家人。
