In 1884, [[William Thomson, 1st Baron Kelvin]], delivered twenty lectures on [[molecular dynamics]] and the [[wave theory of light]].<ref>Robert Kargon and Peter Achinstein (1987) ''Kelvin's Baltimore Lectures and Modern Theoretical Physics: historical and philosophical perspectives'', [[MIT Press]] {{ISBN|0-262-11117-9}}</ref> In their 1987 book ''Kelvin's Baltimore Lectures and Modern Theoretical Physics: historical and philosophical perspectives'', Robert Kargon and Peter Achinstein write<ref>Page 2</ref> that the sessions, which were held in a small lecture hall, were conducted as "master classes". The tone was conversational and informal; Kelvin made almost no use of notes ...  Usually Kelvin lectured from one of these standpoints, then engaged the audience in a discussion of the details, then shifted to another of the standpoints for the second part of the lecture. They explain:<ref>Page 1</ref>

<blockquote>The attendees were expected to have advanced knowledge of physics and mathematics. Among them were British physicists [[Lord Rayleigh]] and [[George Forbes (scientist)|George Forbes]]; Professors [[Kikuchi Dairoku|Kikuchi]] and Fujioka of Japan; American instructors in physics from eastern and western colleges, including [[Albert Michelson]] and [[Edward Morley]]; attendees from Canada, Germany, and Russia; and Hopkins faculty and students including [[H. A. Rowland|Rowland]], [[Thomas Craig (mathematician)|Thomas Craig]], [[Fabian Franklin]], [[Henry Crew]], Gustav Liebig, [[Joseph Sweetman Ames]], and [[Christine Ladd-Franklin|Christine Ladd Franklin]].</blockquote>

A record of the twenty classes was made by [[A. S. Hathaway]] and circulated afterwards using [[Mimeograph#Papyrograph|papyrograph]] stencil duplication. It is these notes that were reproduced in 1987 for the publication sponsored by Johns Hopkins Center for the History and Philosophy of Science. In fact Hathaway continued to correspond with Kelvin, who supplemented the notes, and the "Lectures" were eventually broadly circulated in 1904.<ref>[[William Thomson, Lord Kelvin]] (1904) [https://archive.org/details/baltimorelecture00kelviala Molecular dynamics and the wave theory of light], twenty lectures transcribed by A.S.
