%X The H1 Collaboration reports the first measurement of the 1-jettinessevent shape observable  in neutral-current deep-inelasticelectron-proton scattering (DIS). The observable  is equivalent to a thrust observable defined in the Breit frame.The data sample was collected at the HERA ep collider in the years 2003-2007 with center-of-mass energy of √s=319 GeV, corresponding to an integrated luminosity of 351.1 pb<sup>−1</sup>. Triple differential cross sections are provided as a function of τ<sub>1</sub><sup>b</sup>, event virtuality Q<sup>2</sup>, and inelasticity y, in the kinematic region Q<sup>2</sup> > 150 GeV<sup>2</sup>.Single differential cross section are provided as a function of τ<sub>1</sub><sup>b</sup> in a limited kinematic range.Double differential cross sections are measured, in contrast, integrated over τ<sub>1</sub><sup>b</sup> and represent the inclusive neutral-current DIS cross section measured as a function of Q<sup>2</sup> and y.The data are compared to a variety of predictions and includeclassical and modern Monte Carlo event generators, predictions in fixed-orderperturbative QCD where calculations up to <i>O</i>(α<sub>s</sub><sup>3</sup>) areavailable for τ<sub>1</sub><sup>b</sup> or inclusive DIS, and resummed predictions atnext-to-leading logarithmic accuracy matched to fixed orderpredictions at <i>O</i>(α<sub>s</sub><sup>2</sup>).These comparisons reveal sensitivity of the 1-jettiness observable to QCD partonshower and resummation effects, as well as themodeling of hadronization and fragmentation.Within their range of validity, the fixed-order predictions provide a good description of the data.Monte Carlo event generators are predictive over the full measured rangeand hence their underlying models and parameters can be constrained by comparing to the presented data.
