The compressed tablet looks inevitable only in hindsight. It was invented by a painter, industrialised by machine builders, given physics by metallurgists and given manners by formulation scientists. These are the names and the years, credited. Where a date is disputed, we say so.
For centuries the solid dose was the pill: moistened powder rolled by hand on a pill tile, then often sugar-coated in a pan to hide taste and add gloss. Every dose depended on the apothecary's wrist. Nothing was metered by machine, and no two pills were obliged to be alike.
William Brockedon — painter, Alpinist, Fellow of the Royal Society, and inventor from Totnes — patents the compression of powders in dies: sodium and potassium carbonates pressed into pills and lozenges, and plumbago compressed in vacuo into pencil lead free of grit. The same mechanism served medicine and drawing. A century later The Chemist and Druggist (1954) named him plainly: inventor of the compressed tablet.

Wilhelm Fette starts a precision-tool business that becomes one of the defining tablet-press houses. The first tablet press of Fette's own design follows in 1948; the company (today Fette Compacting, Schwarzenbek) builds the high-speed rotary presses that anchor modern production lines.

Emil Korsch establishes the Berlin machine works that will bear his name; the first tablet press of its own development follows in 1934. Korsch AG remains a Berlin company and one of the reference names in compression technology — the machine-builder's half of the craft.

In Liverpool, the machinery side of Thompson & Capper becomes Manesty Machines, the great British name in rotary presses and coating equipment (B3B, Betapress and their successors). Sources disagree on the founding year — 1920 for the machinery identity, 1935 for the formal limited company — so we give both. The lineage continues today inside Syntegon's press programme.

At the University of Wisconsin, Dale E. Wurster develops the air-suspension coating technique: particles held aloft on an air stream while coating solution is sprayed onto them. His foundational patent (US 2,648,609, assigned to the Wisconsin Alumni Research Foundation) is filed in January 1949 and granted in August 1953; the landmark paper, "Air-Suspension Technique of Coating Drug Particles", follows in the Journal of the American Pharmaceutical Association in 1959. The Wurster fluid-bed insert remains the standard geometry for functional particle coating.

Sugar coating was an artisan's full day of ladling and drying. Sprayed polymer films — later dominated by cellulose derivatives such as HPMC — cut coating to hours, added tens of microns instead of half the tablet's weight, and made functional coats routine: taste-masking, moisture barriers and enteric layers that open only in the intestine.
Metallurgist R.W. Heckel publishes a density–pressure relationship for powder compaction that formulation scientists adopt as the Heckel plot: a way to read, from compression data, how a powder yields, rearranges and bonds. Tablet development gains a quantitative instrument — the press stops being only a machine and becomes a measuring device.

New excipient grades — spray-dried lactose, microcrystalline cellulose — flow and compact well enough to skip granulation entirely. Direct compression, the shortest path from blend to tablet, moves from wish to workhorse; wet and dry granulation remain for the powders that refuse to cooperate.
A tablet that merely contains the dose is not enough — it must release it. Around 1970 the US Pharmacopeia adopts its first official dissolution tests, and the rotating basket and paddle become the tablet's final exam: release the API at the expected rate, in vitro, before anyone is asked to swallow it.
Rotary presses grow into instrumented systems exceeding a million tablets per hour, monitoring punch forces on every station. In 2004 the US FDA's Process Analytical Technology (PAT) framework pushes the industry to design and measure quality into the process rather than testing it in at the end — formulation and machine data finally meet.

Blending, granulating, drying, pressing and coating begin to run as one uninterrupted line with real-time control, and the mid-2010s bring the first regulatory approvals of tablets made continuously rather than in batches. The craft's unit operations stay; their boundaries dissolve.
Panacea Biopharmatec is founded by Bogdan Dicoias as the API manufacturing technology sister of Panacea Biochem: the Panacea house whose entire subject is the craft above — formulation, granulation, compression, coating, excipients, uniformity, dissolution. It inherits no machine and no patent from the names on this page; it inherits their standard, which is the only inheritance that matters: measure honestly, credit precisely, and let the powder set the terms.
