From a Wall Street Journal online review:
Not until July 16 did Edison feel that he had a device worth patenting. The application he signed that day specified multiple timpani that “reproduced” vocal inflections and a sibilant-sensitive diaphragm. But a laboratory visitor (spying for Bell) found the instrument more powerful than clear, with the word schism sounding more like kim.
“We have had terrible hard work on the Speaking telegraph,” Batchelor complained to his fellow inventor Ezra Gilliland. For the past five to six weeks, he added, Edison’s team had been “frequently working 2 nights together until we all had to knock off from want of sleep.”
Thomas Alva Edison’s self-proclaimed greatest invention, the phonograph, won him overnight fame. Journalists would marvel that such an acoustic revolution, adding a whole new dimension to human memory, could have been accomplished by a man half deaf in one ear and wholly deaf in the other.
In February 1877, the same month that saw Edison turn 30 and show his first streaks of silver hair, he and his fellow inventor Charles Batchelor began a new series of experiments on what they called, variously, the “telephonic telegraph,” the “speaking telegraph” and the “talking telephone.”

FINICKY WESTERN EATERS would still be relieved to find filet mignon on the French menu of the hotel, now known as the Nikko Kanaya, a 90-minute drive from Tokyo. The dining room itself looks much as it did when it first opened, in 1893 and eagle-eyed diners might notice that the wooden pillars are decorated with flower carvings that echo those of the nearby Toshogu shrine. The views from the guest rooms are likewise unchanged—forest-covered mountains in the background, the same fastidiously manicured gardens in the foreground that the Einsteins strolled in 1922. Other parts of the hotel feel mildly haunted, like a Japanese version of “The Shining.” The wood-paneled lobby is well worn, stairwells creak noticeably and a shadowy cocktail bar features fading black-and-white photos of forgotten ’20s parties, with men in tuxedos and women in frocks smiling at the camera.

Part of the luxury hotel chain Les Airelles, Le Grand Contrôle is named for the building it will occupy—a 17th-century structure once used as the finance hub of the palace. The hotel will have 14 rooms, some of them apartments, as well as a wellness center, indoor swimming pool, and an Alain Ducase restaurant.

Amazingly, this high-end home was constructed for an unbelievable budget of only US$25,000, a testament to Saul’s perseverance with the DIY build and the couple’s clever sourcing of materials. That means this entire home was built for around the same amount of money that the couple would normally spend on one years rent living in San Diego.
