Answer the question at the end by quoting:

Baker was born into a staunch Methodist family, the youngest son of Birmingham Gas Department's chief accountant, Charles Frederick Baker and Millie Baker. His early schooling was at King Edwards Grammar School. His elder brothers, Leonard and Norman studied law, and he had a sister, Edna who was the oldest of them all. In his teens Baker began to question what religion meant to him and decided to become a Quaker, since it was closer to what he believed in.
While at Pithoragarh, Baker found his English construction education to be inadequate for the types of issues and materials he was faced with: termites and the yearly monsoon, as well as laterite, cow dung, and mud walls, respectively, Baker had no choice but to observe and learn from the methods and practices of vernacular architecture. He soon learned that the indigenous architecture and methods of these places were in fact the only viable means to deal with local problems. Inspired by his discoveries (which he modestly admitted were 'discoveries' only for him, and mere common knowledge to those who developed the practices he observed), he realized that unlike the Modernist architectural movement that was gaining popularity at the time denouncing all that was old just because it was old didn't make sense. Baker adopted local craftsmanship, traditional techniques and materials but then combined it with modern design principles and technology wherever it made sense to do so. This prudent adoption of modern technology helped local architecture retain its cultural identity and kept costs low due to the use of local materials. It also revived the local economy due to the use of local labour for both construction of the buildings and for manufacture of construction materials such as brick and lime surkhi. Baker built several schools, chapels and hospitals in the hills. Eventually, as word spread of his cost-effective buildings more clients from the plains started to contact Baker. One of the early clients was Welthy Fisher, who sought to set up a 'Literacy Village' in which she intended to use puppetry, music and art as teaching methods to help illiterate and newly-literate adults add to their skills. An ageing woman who risked her health to visit Laurie, she refused to leave until she received plans for the village. More and more hospital commissions were received as medical professionals realised that the surroundings for their patients were as much a part of the healing process as any other form of treatment, and that Baker seemed the only architect who cared enough to become familiarised with how to build what made Indian patients comfortable with those surroundings. His presence would also soon be required on-site at Ms. Fisher's "Village," and he became well known for his constant presence on the construction sites of all his projects, often finalising designs through hand-drawn instructions to masons and labourers on how to achieve certain design solutions.

Where did he do most of his work?

Answer the question at the end by quoting:

Nikolai Ivanovich Yezhov, IPA: [njIka'laj jI'zof]; May 1, 1895 - February 4, 1940) was a Soviet secret police official under Joseph Stalin who was head of the NKVD from 1936 to 1938, during the most active period of the Great Purge. Having presided over mass arrests and executions during the Great Purge, Yezhov fell from Stalin's favour and power. He was arrested, confessed to a range of anti-Soviet activity, later claimed he was tortured into making the confessions, and was executed in 1940.
Yezhov was appointed People's Commissar for Water Transport on April 6, 1938. Though he retained his other posts, his role as grand inquisitor and extractor of confessions gradually diminished as Stalin retreated from the worst excesses of the Great Purge. By saddling him with the extra job, Stalin killed two birds with one stone: Yezhov could correct the water transportation situation with tough Chekist methods, and his transfer to the terra incognita of economic tasks would leave him less time for the NKVD and weaken his position there, thus creating the possibility that in due course he could be removed from the leadership of the punitive apparatus and replaced by fresh people. Contrary to Stalin's expectations, the vast number of party officials and military officers lost during Yezhov's purges had been only partially made good by replacement with trusted Stalinist functionaries, and he eventually recognized that the disruption was severely affecting the country's ability to coordinate industrial production and defend its borders from the growing threat of Nazi Germany. Yezhov had accomplished Stalin's intended task for the Great Purge: the public liquidation of the last of his Old Bolshevik political rivals and the elimination of any possibility of "disloyal elements" or "fifth columnists" within the Soviet military and government prior to the onset of war with Germany. From Stalin's perspective, Yezhov (like Yagoda) had served his purpose but had seen too much and wielded too much power to be allowed to live. The defection to Japan of the Far Eastern NKVD chief, Genrikh Lyushkov on June 13, 1938, rightly worried Yezhov, who had protected Lyushkov from the purges and feared he would be blamed.

how old was he when he fell from power?
