Review: Heroes of the Telegraph by John Munro (1891), iBookstore, free

Had blogs existed 120 years ago John Munro would have been up there with the best of 'em. His book, which traces electronic communications from the 50-year-old and "perfected" telegraph through to the latest modern developments, the telephone and the phonograph, is a Gutenberg gem. At the time of writing in 1891 both the telephone and phonograph had been around for little more than 10 years and Munro exhibits the sort of enthusiasm now associated with the latest technical news on Engadget or TechCrunch.

Edison and phonographThe story of the invention of the phonograph by Thomas Edison is fascinating enough, but it is Munro's conjectures on the future opened up by recordings that are much more interesting. Here is a review of possible future developments, some uncannily accurate, some wide of the mark, that make for gripping reading. 

He suggests that phonograph records could be used for correspondence, for dictation and for communication "on unsteady vehicles such as trains" where writing is difficult. He also foresees audio books and reports that Edison can fit the whole of Nicholas Nickleby on four eight-inch wax cylinders of five-inch diameter. "Perhaps," he says, "we could have circulating libraries which issue phonograms, and there is already some talk of a phonographic newspaper which will prattle politics and scandal at the breakfast-table. Addresses, sermons, and political speeches may be delivered by the phonograph; languages taught, and dialects preserved; while the study of words cannot fail to benefit by its performance."

Strangely, in 1891, the concept of recording music was not mainstream: "Musicians will now be able to record their improvisations by a phonograph placed near the instrument they are playing."

This book is a delight and is a must-read for all technophiles.  It has probably been out of print for decades, yet through the Gutenberg project and Apple's iBookstore we can read it again. Much of the book is concerned with the development of the electric telegraph and, of particular interest, the trials and tribulations of undersea cable laying.

After the break is a fuller excerpt from the chapter on Edison's invention of the phonograph.

Leica 135mm f/4 Elmar: Bargain telephoto for the M

One of the big advantages of adopting the M system, or using M adaptors on mirrorless cameras, is the incredible range of available lenses at almost any price point. The early 1960s 135mm f/4 Elmar is an effective telephoto choice at a bargain price...
