&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;John H. Couture&amp;#039;&amp;#039;&amp;#039; is an American engineer and high-voltage experimenter who spent many years reducing [[Tesla Coil|Tesla coil]] design to an explicit, calculable engineering discipline. Writing as J. H. Couture and trading as JHC Engineering Co. of San Diego, California, he produced a sequence of design manuals, construction guides and a computer design program that became standard working references among independent coil builders. His work belongs to the independent-inventor side of [[Tesla Technology|Tesla technology]] research rather than to any university programme.&lt;br /&gt;
&lt;br /&gt;
==Biography==&lt;br /&gt;
Little is published about Couture&amp;#039;s personal life. He is identified in the 1992 International Tesla Symposium programme as &amp;quot;John Couture PE&amp;quot;, indicating a licensed professional engineer, and his publications were issued from his own imprint, JHC Engineering Co., at a San Diego, California address. His books and articles appeared through the late 1980s and the 1990s and circulated through Tesla-community booksellers and the International Tesla Society.&lt;br /&gt;
&lt;br /&gt;
==Scientific contributions==&lt;br /&gt;
Couture&amp;#039;s central contribution was to treat the Tesla coil as an engineering artefact with a defined parameter set rather than as a matter of builder&amp;#039;s intuition. Coil performance had traditionally been reported in the crudest possible terms &amp;amp;mdash; the length of the spark it would throw &amp;amp;mdash; and Couture&amp;#039;s writing repeatedly returns to the question of what that measurement actually means. His 1989 article &amp;quot;Tesla Voltage vs. Sphere and Streamer Sparks&amp;quot;, published in the International Tesla Society journal &amp;#039;&amp;#039;Extraordinary Science&amp;#039;&amp;#039;, addresses precisely the practice of using spark length as the sole description of a coil&amp;#039;s output, and distinguishes the different discharge regimes that produce it.&lt;br /&gt;
&lt;br /&gt;
The design work culminated in JHCTES, a computer-aided Tesla coil design program. Couture identified an explicit list of coil input and output parameters &amp;amp;mdash; 36 in the earlier documentation, 46 in the later &amp;#039;&amp;#039;JHCTES Tesla Coil Notebook&amp;#039;&amp;#039; &amp;amp;mdash; and organised the design task as the problem of choosing a consistent set of them. The accompanying &amp;#039;&amp;#039;Tesla Coil Design Manual&amp;#039;&amp;#039; presents the same material graphically, with 26 design graphs covering coils producing sparks from one inch to 400 inches, so that a builder without the software could still work from published curves rather than from trial and error. The &amp;#039;&amp;#039;Tesla Coil Construction Guide&amp;#039;&amp;#039; (1994) covers the practical side, describing the building of coils in the one-inch to eight-foot spark range.&lt;br /&gt;
&lt;br /&gt;
Taken together the three books and the program address the recurring complaint of the amateur high-voltage community: that Tesla&amp;#039;s own writings and the surviving literature give a builder no systematic way to predict what a given geometry will do. Couture&amp;#039;s answer was a closed parameter model that could be solved in either direction, from desired output back to component values or from components forward to expected performance. On this wiki his paper &amp;quot;[[A New Tesla Coil Design Approach]]&amp;quot; (1992) sits alongside the work of [[James F Corum]], [[Gary L Peterson]] and [[Gary L Johnson]] as part of the practical, measurement-oriented core of the Tesla tradition.&lt;br /&gt;
&lt;br /&gt;
==Conference appearances==&lt;br /&gt;
Couture presented at the International Tesla Society symposia in Colorado Springs, the annual gathering whose proceedings were edited by [[Steven R Elswick]] and whose successor event is the ExtraOrdinary Technology Conference run by [[Tesla Tech]]:&lt;br /&gt;
