George G. André

George G. André, often listed as George Guillaume André, wrote technical books in the late 19th century on mining, blasting, and drawing. Catalog and library records connect his name with works including A Practical Treatise on Coal Mining, Rock Blasting, A Descriptive Treatise on Mining Machinery, Tools and Other Appliances Used in Mining, and The Draughtsman's Handbook of Plan and Map Drawing.

His published work points to a writer deeply engaged with the engineering and industrial world of his time. A Practical Treatise on Coal Mining appeared in the 1870s and later editions followed, suggesting that it was considered useful enough to keep in circulation. Some records also style him with the initials "F.G.S.," which likely indicates a professional scientific affiliation, though the exact details are not clear from the sources reviewed.

Reliable biographical information about his personal life appears to be scarce online, so much of his profile today comes through his books rather than through a well-documented life story. Even so, the range of his subjects shows an author interested in turning technical practice into organized, readable instruction.
