History

The papermaker James Whatman the Elder (1702–1759) founded the Whatman papermaking enterprise in 1740 in Maidstone, Kent, England. He made revolutionary advances to the craft in England and is credited [2] as the inventor of wove paper (or Vélin), an innovation used for high-quality art and printing. His son, James Whatman the Younger (1741–1798), further developed the company's techniques. [3] At a time when the craft was based in smaller paper mills, Whatman innovations led to the large-scale and widespread industrialisation of paper manufacturing.

John Baskerville (1707–1775), who needed paper that would take a light impression of the printing plate, approached Whatman; the resultant paper was used for the edition of Virgil's poetry, embellished with Baskerville's typography and designs. [3] The earliest examples of wove paper, bearing his watermark, appeared after 1740. [4]

The Whatman business is credited with the invention of the wove wire mesh used to mould and align pulp fibres. [2] This is the principal method used in the mass production of most modern paper. The Whatmans held a part interest in the establishment at Turkey Mill, near Maidstone, after 1740; [1] this was wholly acquired through the elder Whatman's marriage to Ann Harris. [2]

"Handmade" paper bearing the Whatman's mark continued in production for special editions and art books [3] until 2002. [5]

Acquisition

On 4 February 2008 GE Healthcare, a unit of General Electric, acquired Whatman plc at 270p per share in cash for each Whatman share, valuing Whatman at approximately £363 million (approximately $713 million.) Last production at Maidstone (Springfield Mill) occurred on 17 June 2014. [5]
