We present infrared aperture masking interferometry (AMI) observations ofnewly formed dust from the colliding winds of the massive binary systemWolf-Rayet (WR) 137 with JWST using the Near Infrared Imager and SlitlessSpectrograph (NIRISS). NIRISS AMI observations of WR 137 and apoint-spread-function calibrator star, HD~228337, were taken using the F380Mand F480M filters in 2022 July and August as part of the Director'sDiscretionary Early Release Science (DD-ERS) program 1349. Interferometricobservables (squared visibilities and closure phases) from the WR 137"interferogram" were extracted and calibrated using three independent softwaretools: ImPlaneIA, AMICAL, and SAMpip. The analysis of the calibratedobservables yielded consistent values except for slightly discrepant closurephases measured by ImPlaneIA. Based on all three sets of calibratedobservables, images were reconstructed using three independent software tools:BSMEM, IRBis, and SQUEEZE. All reconstructed image combinations generatedconsistent images in both F380M and F480M filters. The reconstructed images ofWR 137 reveal a bright central core with a $\sim300$ mas linear filamentextending to the northwest. A geometric colliding-wind model with dustproduction constrained to the orbital plane of the binary system and enhancedas the system approaches periapsis provided a general agreement with theinterferometric observables and reconstructed images. Based on a colliding-winddust condensation analysis, we suggest that dust formation within the orbitalplane of WR 137 is induced by enhanced equatorial mass-loss from the rapidlyrotating O9 companion star, whose axis of rotation is aligned with that of theorbit.
