Yet newly discovered diaries, written in a secret code by his father, show that long before A Brief History of Time became a fixture on millions of bookshelves, the young Hawking was a source of paternal anxiety.<\/p>\n
His father, Frank Hawking, worried that his son lacked drive. Writing in January 1961, when Stephen was 19 and an undergraduate at Oxford, he confided to his journal: \u201cWe are a little worried at the way Stephen is turning out. He hangs round the house with little initiative and does not study much.\u201d<\/p>\n

The private papers of Frank and Isobel Hawking, Stephen\u2019s parents, were uncovered during research for the first authorised biography of the physicist, to be released by the publisher John Murray in September.<\/p>\n
Hawking, who died in March 2018 aged 76, became a symbol of academic brilliance and human resilience. Diagnosed with motor neurone disease at 21 and initially given only two years to live, he gradually lost the ability to move and speak, eventually communicating through a voice synthesiser.<\/p>\n
His work on black holes and gravity made him one of the most recognisable scientists, while A Brief History of Time sold more than 13 million copies.<\/p>\n
The diaries suggest, however, that at home he was not always seen as a figure of unstoppable promise.<\/p>\n
In January 1961, Frank, an expert in tropical diseases, voiced concerns that his son was not working hard enough. \u201c[Isobel] says he has an inferiority complex to me (he has no need to) and he has lost faith in physics at Oxford, thinking it is inferior to arts,\u201d he wrote. \u201cThis is a great pity if so. At his age I had a burning ambition to get on, and if only I had had half his advantages, I should have done much better.\u201d<\/p>\n
The diaries were discovered hidden away at the home of Stephen\u2019s sister Mary. They were made available to the author Graham Farmelo for the book Hawking: His Life and Work.<\/p>\n
Frank Hawking kept his diary for more than 60 years, often using a code based on Greek script. Farmelo cracked the system and translated more than 200,000 words about Stephen\u2019s childhood, illness, marriages and career.<\/p>\n

In his diaries, Frank wrote: \u201cThis journal was originally written in Greek script to form a simple secret code and so secure greater privacy, which is essential for a journal which may fall into the hands of enemies or easily wounded intimates.\u201d<\/p>\n
