# Dr. Samuel Ferguson — Five Weeks in a Balloon character guide > Dr. Samuel Ferguson in Five Weeks in a Balloon by Jules Verne. **Role:** major **Also known as:** Samuel Ferguson, Dr. Ferguson, Ferguson, Doctor Ferguson **First appearance:** 0000-i ## Snapshot The affable, secretive mastermind behind the Victoria, who bets his reputation that a balloon can cross Africa where men on foot have died. ## Who they are Ferguson is the expedition's scientist, commander, and public sensation — a man so approachable that half of London offers to join him, yet so guarded that he refuses every would-be companion and every inventor's steering mechanism without explanation. His calm under crisis (he watches a mirage of his own balloon with quiet amusement, then descends toward a distant pair of palms) masks a fierce, almost stubborn faith in his own design. His friendship with the skeptical Kennedy and his refusal to reveal his secret give the voyage its central tension: will the doctor's calculations hold where so many African expeditions have failed? ## In the story ### [I](https://www.betterreads.dev/discover/five_weeks_in_a_balloon_se/chapters/i) The protagonist, presented at the Royal Geographical Society, whose daring balloon expedition is announced. ### [II](https://www.betterreads.dev/discover/five_weeks_in_a_balloon_se/chapters/ii) The intrepid discoverer whose balloon expedition across Africa is announced; he becomes the lion of the day, affably giving information but refusing all offers of partnership or mechanical guidance systems. ### [III](https://www.betterreads.dev/discover/five_weeks_in_a_balloon_se/chapters/iii) The doctor reveals his secret plan to cross Africa by balloon, defending it with logical arguments and fatalistic philosophy. ### [IV](https://www.betterreads.dev/discover/five_weeks_in_a_balloon_se/chapters/iv) Carefully studies the explorations of Barth, Burton, and Speke to plan his aerial route. ### [Chapter V](https://www.betterreads.dev/discover/five_weeks_in_a_balloon_se/chapters/v) Energetically pushes preparations for departure, studies Arab language and Mandingoe idioms, and argues with Kennedy about the necessity of their expedition. ### [A Servant—Match Him!](https://www.betterreads.dev/discover/five_weeks_in_a_balloon_se/chapters/vi) The doctor calmly oversees the weighing ceremony and notes the weights of his companions for the balloon's balance.
