6 Dec : When Edison recorded – Mary had a little lamb

Do you know when first recording of human voice was done ? More surprising would be that it was a nursery rhyme which we all must have read... Mary had a little lamb.

Till 2008 it was believed that Thomas Edison created the first recording of human voice, reciting “Mary Had a Little Lamb” in 1877. He recited the nursery rhyme Mary Had a Little Lamb. He re-recorded it in 1927 for posterity.

Mary Had a Little Lamb
Mary had a little lamb,
Its fleece was white as snow.
And everywhere that Mary went,
The lamb was sure to go. 

It was discovered in 2008 that Édouard-Léon Scott de Martinville was actually the first man to make a recording of a human voice back in 1860. It was a recording of a person singing part of the French song “Au Clair de la Lune“.

आज 1877 में मशहूर वैज्ञानिक थॉमस एल्वा एडिसन ने पहली बार इंसान की आवाज़ को रिकॉर्ड किया था। इसमें कहा जा रहा था “Mary Had a Little Lamb”। कमसे कम 2008 तक तो यही माना जाता था। तब ये पता चला था कि 1860 में पहली बार सुनाई देने लायक इंसानी आवाज़ की recording संभव हो पाई थी। इस उपकरण का नाम phonautograph था। इससे सिर्फ आवाज़ रिकॉर्ड की जा सकती थी, सुनी नहीं जा सकती थी। साल 2008 में इन रिकॉर्डिंग्स को स्कैन करके कंप्यूटर पर सुना जा सका। इसे आगे चल कर ध्वनि तरंगों पर हुए कई scientific investigations में इस्तेमाल भी किया गया था।
