Inventions, Inventors, Discoveries & Discoverers — Master Reference
The cluster of Inventions, Inventors, Discoveries & Discoverers is one of the highest-yield Everyday Science / General Knowledge topics in Pakistan’s PPSC, FPSC, NTS, CSS, PMS, OTS, CTS, BPSC, KPPSC and SPSC exams. Almost every Junior Clerk, Tehsildar, Assistant, Sub-Inspector, Lecturer and BPS-14 to BPS-17 paper carries 3–6 MCQs from this chapter — and it is core CSS Screening MPT (General Science & Ability) content. This page consolidates 68 solved MCQs covering communications classics (telephone — Bell 1876, telegraph, radio — Tesla 1893, Marconi 1901, television — Baird 1926, cell phone — Cooper 1973), transport (steam engine — Watt 1765, automobile — Benz 1885, airplane — Wrights 1903, helicopter, jet engine — Whittle 1937), power and electronics (battery — Volta 1800, dynamo — Faraday 1831, AC motor — Tesla 1888, transistor 1947, integrated circuit, microprocessor 1971), life-savers (vaccination — Jenner 1796, pasteurisation, polio vaccine — Salk 1952, MRI — Damadian 1977), and the great discoveries in particle physics (X-rays — Röntgen 1895, electron — Thomson 1897, neutron — Chadwick 1932), biology (cell — Hooke 1665, blood circulation — Harvey 1628, blood groups — Landsteiner 1900, DNA double helix — Watson & Crick 1953) and chemistry (periodic table — Mendeleev 1869, atomic numbers — Moseley 1914). For wider context, see Wikipedia: Timeline of Historic Inventions and the official Nobel Prize Laureate List.

Famous “Anchor Facts” — Most Tested in Exams
- Bell = Telephone; Edison = Light bulb + Phonograph + Cinema (with Lumière).
- Tesla = Radio + AC motor; Marconi = transatlantic radio telegraphy (1901).
- Wright brothers = Airplane (1903); Whittle = Jet engine (1937).
- Volta = Battery (1800); Faraday = Dynamo + Electromagnetic induction.
- Mendeleev = Periodic table; Moseley = atomic numbers correction.
- Newton = Laws of motion + Gravity (1687).
- Galileo = Thermometer (1593) + improved Telescope (1610).
- Lippershey = first Telescope (1608).
- Torricelli = Mercury barometer (1643).
- Fahrenheit = Mercury thermometer (1714); Celsius = Centigrade thermometer (1742).
- Hooke = Cell discovery (1665); Harvey = Blood circulation (1628).
- Watson & Crick = DNA double helix (1953); Miescher = DNA discovery (1869).
- Landsteiner = Blood groups (1900).
- Röntgen = X-rays (1895); Becquerel = Radioactivity (1896).
- Thomson = Electron (1897); Rutherford = Proton (1919); Chadwick = Neutron (1932).
- Anderson = Positron (1932); Villard = Gamma rays (1900).
- Jenner = Smallpox vaccine (1796); Salk = Polio vaccine (1952).
- Pasteur = Pasteurisation (1862); Fleming = Penicillin (1928).
- Banting & Best = Insulin (1921).
- Cooper = Cell phone (1973); Engelbart = Computer mouse (1963).
- Damadian = MRI scanner (1977); Greatbatch = Pacemaker (1958); Jarvik = Artificial heart (1978).
- Fermi = first nuclear reactor (1942).
- Townes = Laser (1960); Kapany = Fibre optics (1955).
- Shockley, Bardeen, Brattain = Transistor (1947, Bell Labs).
- Gutenberg = movable-type printing press (~1445).
- Ørsted = Electromagnetism (1820); Sturgeon = Electromagnet (1824).
Exam tip: Memorise inventor + year together (Bell-1876, Edison-1879, Wrights-1903, Röntgen-1895, Fleming-1928). Examiners commonly substitute either the wrong inventor (Tesla vs Edison) or the wrong year — locking the pair eliminates both traps.
Frequently Asked Questions
