In 1650 he was elected first scholar of that year at King's College, Cambridge, his elder brother William being elected sixth; he, however, changed places with his brother (Harwood, Alumni Eton. p. 247). He was elected fellow of his college in 1654.
Janeway's religious impressions date from 1652, when he came under the influence of a puritan fellow-student. From this time he devoted himself to the fostering of evangelical piety, especially among his own relatives. He left Cambridge in consequence of the illness of his father, who had been rector of Ayot St. Lawrence, Hertfordshire (1644–1646), and was now rector of Kelshall, Hertfordshire. On his father's death in 1654 he returned to King's College, where for some time there had been ‘a private society’ for religious exercises and theological discussion. As the other members left the university, Janeway gave himself to solitary study, thus injuring his health. Benjamin Whichcote [q. v.], then provost of King's College, recommended him as tutor in the family of ‘Dr. Cox,’ i.e. Thomas Coxe, M.D. [q. v.] After a short trial he found the work too heavy, and went for country air to stay with his mother and elder brother at Kelshall. He does not seem to have been ordained, but he preached twice in 1656. He fell into a rapid consumption, and died unmarried at Kelshall in June 1657. He was buried in Kelshall Church; a memorial tablet was placed in 1823 on the south wall of the chancel by John Henry Michell, then rector. Of his seven brothers (all of whom died under forty), William (b. 1631) succeeded his father (19 Oct. 1654) as rector of Kelshall, was ejected in 1662, and seems afterwards to have lived at Buntingford, Hertfordshire; Andrew (b. 1635) was a London merchant; James is separately noticed; Abraham was a preacher in London, where he died of consumption in September 1665.
[James Janeway's Invisibles, Realities, &c., 1673, deals mainly with his brother's religious experiences, and the chronology of the events of his last years is confused and uncertain. This account, somewhat abridged, is reproduced in Clarke's Lives, 1683, pp. 60 (bis) sq.; other abridgments are in Middleton's Biographia Evangelica, 1784, iii. 362 sq.; Brook's Lives of the Puritans, 1813, iii. 271 sq.; and Cox's Hist. of the Janeway Family, prefixed to James Janeway's Heaven upon Earth, 1847; Calamy's Account, 1713, p. 370; Calamy's Continuation, 1727, i. 530, ii. 964; Cussans's Hertfordshire, 1874; Urwick's Nonconf. in Hertfordshire, 1884, pp. 124, 563 sq., 658 sq., 729 sq., 758 sq., 797 sq., gives valuable data, but confuses the elder with the younger William Janeway, as Calamy had done in his Abridgment, 1702, p. 278.]
JANIEWICZ, afterwards YANIEWICZ, FELIX (1762–1848), violinist and composer, was born at Vilna in Lithuania in 1762. He travelled in Europe, visiting Haydn and Mozart in Vienna about 1784, and spending three years in Italy. He made his début as a violinist at a Concert Spirituel, Paris, in December 1787, and was described in the ‘Mercure de France’ as a pupil of Jarnowick (Giornovichj). Janiewicz was immediately recognised by the Parisians as an artist of high rank. For a short time he enjoyed the pension of a musician on the establishment of Mlle. d'Orléans; but on the outbreak of the revolution he left France for London.
Janiewicz played at Corri's house in London in January 1792, and at Growetz's concert on 9 Feb., giving a benefit concert in the same month. He performed his violin concerto at the Saloman concerts of 17 Feb. and 3 May (for Haydn's benefit). During several seasons Janiewicz played in London, visited the provinces and Ireland as a violinist, and conducted the subscription concerts in Manchester and Liverpool. He was one of the original members of the London Philharmonic Society, and in the first season (1813) was one of the leaders of the orchestra. For a time he kept a music-warehouse at 25 Lord Street, Liverpool, and married Miss Breeze of that town in 1800. In 1815 he went to Edinburgh. He retired after 1829, and died at 84 Great King Street, Edinburgh, on 21 May 1848, aged 86.
Janiewicz was not only a brilliant soloist, but an excellent leader and a conductor of conspicuous ability. His style of playing was solid, yet full of expression, and his skill in octave passages admirable. Janiewicz published: 1. ‘Six Divertimentos for Two Violins,’ London, 1800? 2. ‘Sonata for the Pianoforte, with Accompaniment for the Violin,’ in which is introduced Handel's ‘Lord, remember David,’ London, 1800? 3. ‘Go, youth belov'd,’ song, Liverpool, 1810? 4. ‘Polish Rondo for Pianoforte,’ Liverpool, 1810? and many adaptations.

JANSSEN or JANSEN, BERNARD (fl. 1610–1630), stonemason and tombmaker, a native of Holland, was in all probability a pupil of Hendrik de Keyser, the great sculptor and tombmaker at Amsterdam. He is sometimes described as an architect and the designer of Northampton (afterwards North-
