&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Harry George Armstrong&amp;#039;&amp;#039;&amp;#039; (February 17, 1899 – February 5, 1983) was a pioneering [[aerospace medicine]] specialist, particularly in the area of [[human factors]] in [[aviation]]. He authored the book &amp;#039;&amp;#039;Principles and Practice of Aviation Medicine&amp;#039;&amp;#039;, which is considered a classic in the field.&lt;br /&gt;
&lt;br /&gt;
== Early life and education ==&lt;br /&gt;
Armstrong was born in [[Laurel, Nebraska]]. He attended the [[University of Nebraska]] and received his medical degree from [[Creighton University]] in 1925.&lt;br /&gt;
&lt;br /&gt;
== Career ==&lt;br /&gt;
In 1926, Armstrong joined the [[United States Army Air Corps]], where he began his career in aviation medicine. He was instrumental in establishing the [[Aerospace Medical Research Laboratory]] in [[Dayton, Ohio]], and served as its director from 1935 to 1940.&lt;br /&gt;
&lt;br /&gt;
In 1941, Armstrong was appointed as the first Surgeon General of the [[United States Air Force]]. During his tenure, he implemented many improvements in the medical care of Air Force personnel, including the establishment of the [[School of Aviation Medicine]] at [[Randolph Field]], Texas.&lt;br /&gt;
&lt;br /&gt;
Armstrong&amp;#039;s research in the field of aviation medicine led to many significant discoveries. He developed the concept of the &amp;quot;Armstrong&amp;#039;s Line,&amp;quot; a physiological boundary above which humans cannot survive without a pressure suit. He also conducted research on the effects of high altitude on human physiology, and developed methods for preventing and treating [[decompression sickness]].&lt;br /&gt;
&lt;br /&gt;
== Legacy ==&lt;br /&gt;
Armstrong&amp;#039;s contributions to aviation medicine have had a lasting impact on the field. His book, &amp;#039;&amp;#039;Principles and Practice of Aviation Medicine&amp;#039;&amp;#039;, is still widely used as a reference in the field. The [[Harry G. Armstrong Award]] for Excellence in Aerospace Medicine is named in his honor.&lt;br /&gt;
